Message from your Chairman...<br />

A NEW FUTURE FOR THE AWD<br />

I would like to say ‘thank you’, to all the Membership for electing me to the<br />

post as your National Chairman. I have been closely involved in the welding<br />

distribution industry both at BOC and as Managing Director of Weldability-Sif.<br />

I hope this past experience will stand me in good stead as your new Chairman.<br />

WELCOME<br />

I further would like to thank my predecessor Danny Gallagher, on behalf of the AWD Council and all the<br />

members, for his tremendous work, commitment and enthusiasm during his Chairmanship. He has served<br />

the AWD and the Council well for over 11 years.<br />

When I started my career in the Welding Industry back in the 70’s it was a time of much change. It in<br />

fact was the very moment when the manufacturers became focused on the distributive trade for its<br />

pathway to service industry. Most Welding Product brands of the time were delighted for the opportunity<br />

to cut their operational costs and support their preferred distributor route to market. Sadly some of those<br />

brands today now support the notion that only 60% of sales should go via the distributor and 40% should<br />

go direct. 33 years on and is this repeating pattern the new direction of the Welding Distribution industry?<br />

I am certain that many of my fellow AWD Members today can be satisfied that their fellow AWD<br />

Members, who often own major product brands, still believe that supplies to the Distributive trade<br />

remains the only route to market. It is those values that will help us ensure a positive and mutuallysuccessful<br />

future for our market.<br />

I am happy to report that since announcing the need to form 3 new working groups at the AWD<br />

conference in April, the groups have been formed with the first meeting of the PSQ (Product Safety and<br />

Quality) committee in particular, taking place on the 4th July. Each of the groups will play an active role<br />

in delivering information and constructive assistance to the Membership and help the industry develop<br />

its professionalism and relevance still further.<br />

Projects within the UK’s Renewable Energy sector strategy and structure will remain central to the future<br />

of the Welding Industry and provide us all with many new opportunities for investment, innovation and<br />

profit. The AWD is aligning itself with many of these projects in order to assist Members in developing<br />

local contacts to supply. The AWD’s strongest marketing tool is the “Welding Wo<strong>rld</strong>” brand which is<br />

being trademarked and is clearly promoted by our magazine and exhibition. Your continued support of<br />

these activities should be seen as time and money well spent in investing in a brighter future in more<br />

ways than one!<br />

Our Membership Manager, Wendy Barber, is busily contacting each Member and establishing how<br />

exactly the AWD can make a difference to your business. Many are taking the opportunity to use the<br />

magazine and website to advertise and as both of these become more central to industry-wide<br />

communication, your membership status is further enhanced.<br />

We must act as an Association representing the needs of its Members and to take control of promoting<br />

all that is good about our industry, including good practice and products, eradication of bad practices<br />

and putting forward the long-term benefits of more professional welders.<br />

We, the AWD National Executive, National Council and Regional officers are well on the way to delivering<br />

many of our best intentions and we thank you for your continued support in doing so.<br />

AGM & CONFERENCE<br />

The Secretary and Treasurer reports were presented. The annual election of officers took place with Adrian<br />

Hawkins, Weldability-SIF appointed Chairman, Phil Tranter, Air Products appointed Vice-Chairman with Helen<br />

Brewin, Proactive Gas Safety Ltd elected to the Council.<br />

The new Chairman presented an overview of the Association and future important developments including: -<br />

1. The Association’s need for a modern modus operandi to take advantage of a major re-investment in<br />

manufacturing and training skills, with a large part directed at the welding industry.<br />

2. The need to move away from being a one person centred association providing a handful of complicated<br />

Member benefits and the odd Conference and Regional meeting, to a diverse and valuable collective<br />

organisation with a multitude of skills.<br />

3. The “Welding Wo<strong>rld</strong>” brand to be trademarked and clearly promoted by the magazine and exhibition.<br />

4. The AWD to act as an Association representing its Members’ needs and controlling the promotion of all<br />

that is good about the industry, eradicating some of the bad practices, emphasizing the long term benefit<br />

of more professional welders and the promotion of best practice and best products.<br />

5. The AWD’s need to create a support base to access Parliamentary assistance and discussion, product<br />

and process research and support, lobbying government and industry power bases and the creation of a<br />

series of 3 Working Groups with the first Product Safety and Quality meeting on the 4th July 2011.<br />

Vice Chairman, Phil Tranter gave a presentation on the AWD Marketing intentions and why they are so important.<br />

Wendy Barber, new Membership Manager gave a presentation on how she will be contacting every member<br />

and potential new members over the coming weeks and months.<br />

After the AGM the conference began with Doug Thornton, Chief Executive of the British Compressed Gases<br />

Association giving a presentation on the ‘BCGA and Welding Matters’, followed by an enlightening presentation<br />

by Graham Dodd of Crewe Hall and Local Historian, who gave an outline of the history of Crewe Hall, highlighting<br />

key features, inhabitants and events.<br />

AWD Chairman, Adrian Hawkins closed the proceeding by thanking the sponsors, secretariat, speakers and<br />

membership for supporting the AGM and Conference through time and effort they had put into their presentations.<br />

A-Plant Eye in the Sky Helps Catch Plant Thieves in Cross Country Recovery Operation<br />

The incredible recovery record of A-Plant’s A-Trak GPS satellite tracking and<br />

security system used to protect the machines in the company’s hire fleet has been<br />

demonstrated by the successful retrieval of a stolen telehandler following a cross<br />

country recovery operation involving A-Plant, the hiring customer, the Police and<br />

Enigma Vehicle Systems who host the A-Trak system on behalf of A-Plant and all<br />

because of an out-of-hours call reporting the theft of a 12 metre telehandler from a<br />

site in Oldbury, West Midlands.<br />

Asif Latief, A-Plant’s Marketing Director said: “This is a remarkable recovery<br />

operation which was only possible due to the power of the A-Trak system and<br />

fantastic collaboration between the customer, A-Plant, Enigma and the Police. Over<br />

98% of stolen A-Plant equipment protected with A-Trak is recovered, compared to<br />

an industry average of just 5-10%.”<br />

UK MANUFACTURERS REPORT SOLID DEMAND<br />

CBI reports UK manufacturers continue to report healthy order books and expect<br />

further output growth in the coming quarter, though at a slightly slower pace than over<br />

the past few months.<br />

Manufacturing demand remained strong in June. Of the 457 manufacturers responding<br />

to the CBI’s latest monthly Industrial Trends Survey, 27% of manufacturers describe<br />

total orders as above normal, while 26% said they were below normal. The resulting<br />

balance of +1% is well above the long-term average (-18%), and is a slight improvement<br />

on the previous month’s balance of -2%.<br />

Export orders books also picked up slightly in June, with 27% of firms saying they were<br />

above normal, and 27% below normal. The resulting balance of 0% compares with -<br />

3% in May, and is significantly above the long-term average (-21%). It is a continuation<br />

of the broader trend of improvement that has been evident over the past two years.<br />

Manufacturing firms still expect solid growth in output in the coming quarter. While<br />

28% predict output will rise in the coming three months, 14% predict it will fall. The<br />

resulting rounded balance of +13% is down slightly on very strong expectations seen<br />

over the past five months, but still exceeds the long-term average (+5%).<br />

However, price pressures remain a concern, with 31% of manufacturers predicting<br />

they will raise output prices over the coming quarter, and 5% expecting to lower prices.<br />

HMS QUEEN ELIZABETH STEPS OUT INTO THE LIME LIGHT<br />

Construction of the first of the two new aircraft carriers for the Royal Navy, HMS<br />

Queen Elizabeth, took a huge step forward as BAE Systems' Govan yard moved two<br />

giant sections of the hull together for the first time. The structure is so big that it fills<br />

an entire hall at Govan and now extends beyond the doors onto the yard, providing<br />

a spectacular view from across the River Clyde.<br />

It took a team of 20 employees and remote controlled transporters just one hour to<br />

move 1,221 tonnes of steel over 100 metres across the shipyard. The hull section was<br />

then manoeuvred carefully into position to line up with the rest of the block.<br />

Steven Carroll, Queen Elizabeth Class Project Director at BAE Systems’ Surface Ships<br />

division, said: “Seeing the mid section of the carrier come together brings into sharp<br />

focus the sheer scale and complexity of this engineering feat.<br />

“With construction underway at six shipyards across the country, it is one of the<br />

biggest engineering projects in the UK today – second only to the London 2012<br />

Olympics – and we’re all very proud to be a part of it.”


JCB SECURES MULTI<br />

MILLION DIGGER DEAL<br />

JCB has announced deals worth almost £20 million from two leading UK<br />

Hire Companies.<br />

The first order is to supply 350 machines to plant hire company, Kent-based<br />

H.E. SERVICES Group, who has ordered a range of JCB products including<br />

mini excavators, Loadall telescopic handlers, 3CX backhoe loaders, skid<br />

steer loaders and tracked excavators.<br />

The H.E. SERVICES Group based in Strood, Kent employs more than 1,000<br />

people. As well as its hire business, the company is well known for the<br />

network of ‘Diggerland’ theme parks, where adults and children can enjoy<br />

the experience of driving JCB’s.<br />

The machines ordered include 8018, 8030 and 8065 mini excavators to be<br />

made at JCB Compact Products in Cheadle; 520-40, 535-95, 535-125 and<br />

540-170 Loadall telescopic handlers and 3CX backhoe loaders produced at<br />

Rocester and tracked excavators made at JCB Heavy Products in Uttoxeter.<br />

The second order from Tool Hire - the rental division of Jewson - is for 300<br />

JCB 8014 mini excavators, 100 JCB 8008 micro excavators, and 53 VMT160-<br />

The Manufacturing Institute welcomes Governments<br />

Recognition of importance of UK Manufacturing<br />

The Manufacturing Institute (TMI) has supported the government’s<br />

recognition of the value delivered by the UK’s manufacturing sector, and<br />

the need to ensure that the image of modern manufacturing is vigoursly<br />

communicated to attract more talent to the sector<br />

Myths abound about manufacturing being dead-end, messy and lacking<br />

creativity, with boring assembly lines, poor pay and a lack of esteem for<br />

its workers. There is recognition that manufacturers themselves need to<br />

further improve its image and to open their doors to students and<br />

teachers to tackle this and to further encourage new talent into the<br />

sector<br />

The dot com collapse, followed by the banking crisis and recent<br />

recession has resulted in a long overdue recognition that manufacturing<br />

is crucial to the future prosperity of the UK.<br />

TMI published ‘Manufacturing - the Truth behind the Myths’, that<br />

dispelled the top ten negative views on manufacturing through a series<br />

of case studies from influential and high-profile wo<strong>rld</strong>-class<br />

manufacturers, including Bentley Motors, BAE Systems Submarines,<br />

Siemens and Airbus.<br />

Dr Julie Madigan, Chief Executive, TMI said: “The high standards of<br />

innovation and intellectual challenge in modern UK manufacturing,<br />

together with exacting environmental and ethical production methods<br />

and a high regard for the health, safety and wellbeing of workers, means<br />

that manufacturing is now certainly very much an appropriate choice for<br />

those seeking a rewarding and fulfilling working career.<br />

TWI EXPERTS KEEP FLYING LEGEND AIRBORNE<br />

1940’s engineering and 2011 welding expertise joined forces at TWI recently, in a<br />

combined effort to keep the wo<strong>rld</strong>'s oldest flying jet aircraft in the skies.<br />

A thin sheet stainless steel shroud surrounding the jet pipe of a North American<br />

Aviation F-86A Sabre jet fighter was in need of some specialist attention. This shroud<br />

deflects any leaking exhaust gases away from the internal structure during the brief<br />

period, between start-up and the engine reaching running temperature, when<br />

previously weeping seals around the jet expand and become leakproof.<br />

Although within limits, several small cracks and tears were in need of attention<br />

during the Sabre's annual maintenance if the aircraft was to achieve its Permit to<br />

Fly.<br />

“It's very tricky to weld materials like this but we're lucky here at Duxford” said Roger<br />

King of the Aircraft Restoration Company. 'TWI's experts are almost on our<br />

doorstep.”<br />

Using TIG welding and an appropriate consumable for the aged material, TWI was<br />

able to arrest and repair cracks in the wafer thin material. “It's not a structural part”<br />

clarifies King. “It is a heat deflector.<br />

Had it made a structural contribution a more rigorous and detailed procedure would<br />

have been demanded. New parts no longer exist, so the only alternative to repair<br />

would be to re-manufacture from scratch.”<br />

The Sabre is best known for its service in the Korean War where it was pitted against<br />

the Soviet MiG-15.<br />

The Golden Apple Trust, which owns the Sabre (registered G-SABR), believe it to<br />

be the oldest airworthy jet-powered aircraft in the wo<strong>rld</strong>: its first flight was in<br />

March 1949.<br />

10 INDUSTRY INSIGHT<br />

A series of views from<br />

John Swain, Managing Director,<br />

Anopol Limited<br />

Keeping ContaCt<br />

My modest company has on average a customer data base of 2,500 firms, of which around 600 are active at any one time. Our data base<br />

covers companies which use our services on a regular and periodic basis; services comprising sub-contract stainless steel finishing,<br />

supply of machines and pickle pastes for cleaning welds on stainless steel components and fabrications.<br />

A very real problem facing companies like mine is how to maintain contact with the majority of customers, particularly those whose<br />

requirements are spasmodic. This topic has been raised in sales meetings over a period exceeding 20 years, knowing that the problem<br />

of regular customer contact was becoming more acute with the ever increasing number of customers. The sales force was far too small<br />

to undertake any regular customer contact, so another solution was required.<br />

One of my favourite activities, which has helped to occupy my time over the past forty years, is Public Relations. Unfortunately, the mention<br />

of PR is like waving a red cloth to a bull in the minds of many managers, especially engineers. For some ten years we employed a PR lady<br />

in London part-time at a modest cost. She proved to be brilliant at promoting the company and in raising my personal profile within the<br />

industry. Public Relations encompass a whole range of interesting activities, from producing advertisements to having press releases<br />

and articles about the company and its services published.<br />

Every company benefits from good PR. You don’t necessarily need to use an external agent, but telling industry about your company and<br />

what it sells is what PR is all about. Having an informative website or sending out sales literature is another form of PR. Where is all this<br />

leading? Let’s go back to the question of how to maintain contact to many of our old and new customers? It was suggested that I should<br />

use my PR knowledge to edit a regular Newsletter. The success or otherwise of the Newsletter would depend upon its content. It was<br />

agreed that it would have a light side as well as a serious one. Inclusions would not be limited to the company’s activities, but would<br />

encompass items of general interest. A few carefully vetted jokes would also not be out of place.<br />

The Newsletter would be circulated electronically in the first instance, with hard copies being posted with invoices. The circulation list<br />

would also include other parties possibly interested in the company’s activities, for example: the Bank, company accountants and even<br />

some competitors.<br />

The initial response from recipients was encouraging. Some favourable comments were received and no one asked to be removed from<br />

the circulation list. One recipient suggested making the Newsletter a little lighter in tone. Consequently,<br />

more humour was incorporated in subsequent issues. The Newsletter is now entering its third year<br />

and each quarter an average of 1500 companies and individuals receive it electronically or by post.<br />

In March 2010, a random number of 50 recipients of the Newsletter were contacted by email<br />

or telephone by two ladies in the office. They conducted a small survey, posing the following<br />

questions under the guise of whether we should continue with the Newsletter: “Are you<br />

aware that you receive our Newsletter every quarter?” Of the 50 replies 44 were positive<br />

and 6 negative. The second question to the 44 who replied positively: “Can I ask you if you<br />

read it and if so, do you find the contents interesting?” Forty-two replied ‘yes’ and 2 said<br />

‘no’. I am currently working on Issue Number 13.<br />

I am not advocating that all members of AWD should invest in producing a Newsletter.<br />

Few probably have the time or inclination. I am simply stressing the importance of<br />

keeping in touch with both past and present customers. A regular letter or email to<br />

these customers, stating that you are still in business and reminding them of the<br />

services and products you supply may suffice.<br />

FOWLMERE ENGINEERING LTD


WELDING HIGHLIGHTS<br />

Fowlmere engineering ltd<br />

Established some 45 years ago, Fowlmere<br />

Engineering has grown into one of the largest<br />

UK independent welding distributors and the<br />

largest Air Products Gas Agent in Europe.<br />

In September 1992, Arran Nicoll joined the Company,<br />

to help run the business with his brother Rob. For eight<br />

years prior to that, Arran was the Chief Race Engineer<br />

for his other brother Kurt who was an aspiring grand prix<br />

motocross rider.<br />

Arran’s Father bought into the Company in 1973 when it was solely an engineering company. The Company expanded into<br />

the Industrial Gas and Welding distribution business in the late seventies.<br />

When Rob and Arran took over the running of the business in 1992, they made the decision to focus on the distribution side.<br />

In 1995, their Father took a less active role and the engineering side of the business was closed.<br />

To-day Arran and Rob run the company with their parents holding positions as Directors. Their Mother had trained as an<br />

accountant so is able to offer advice on any financial issues and whilst their Father is available for advice through his wealth<br />

of business experience. He is the current FIM Wo<strong>rld</strong> Motocross Race Director, so in this capacity he travels the Wo<strong>rld</strong> for<br />

most of the year.<br />

Fowlmere employs 15 people, with the primary contact for any sales<br />

enquires being either Rob or Arran.<br />

Arran says: “We have a very strong relationship with Air Products<br />

and were their ‘European Agent of the Year in 2008’. Migatronic is<br />

our main supplier of welding equipment alongside Lincoln Electric,<br />

GYS and Mosa. Weldability-Sif is our largest supplier of welding<br />

consumables with additional products coming from Wilkinson Star<br />

and Weldspares, whilst our gas control equipment comprising<br />

regulators and manifolds are supplied by Gas Arc.<br />

Left to right:<br />

Arran Nicoll, Matthias Kuhn (Air Products, General<br />

Manager, UK and Ireland) and Rob Nicoll at Trade counter<br />

Left to right Janice, Melanie and Sarah (Sales/Accounts Office)<br />

We also have a great deal of success in selling abrasive products supplying SIA and Klingspor products. Fume and Dust<br />

Extraction is a rapidly growing market, where we represent Kemper. In November 2010 we added Calor Gas products to<br />

our portfolio, so you can say that we could be looking forward to long cold winters!”<br />

Fowlmere deliver to customers old and new across East Anglia supplying a very varied customer base from large fabricators,<br />

universities and colleges, construction sites, agricultural manufacturers to private farmers and individuals.<br />

At the beginning of 2010, the Company entered into an agreement with Weldability-Sif to create an ecommerce website,<br />

which has increased the Company’s profile on the internet. To see how professional this site is just log onto: -<br />

www.fowlmerewelding.com


Arran continued: “We have a fleet of nine delivery vehicles,<br />

six 7.5t lorries, one 18t lorry, a 26t lorry and a Vivaro van so<br />

consequently we try to deliver on our own transport where<br />

possible, we also have two new vehicles on order an 18t and<br />

a 26t DAF which should be on the road by the start of June<br />

2011. This will give us full control and confidence in the<br />

quality of service we offer. It also means that we maintain<br />

relatively high stock levels to provide our next-day service.<br />

Andy Linwood is our Service Engineer and he handles<br />

machine servicing and breakdowns, whilst Ivor Harvey is our<br />

Gas Control Engineer covering installations and inspections.<br />

Both Rob and I are very competitive people and we get great<br />

Showroom<br />

satisfaction from success. We always maintain our core<br />

values of treating all our customers in the manner in which we would like to be treated ourselves and only supply high<br />

quality products that we both believe in and would be happy to receive ourselves.”<br />

Fowlmere’s employee training centres around safety issues associated with the Air Products gas side of our business which<br />

is very heavily regulated. Both our machine and gas service engineers attend manufacturer’s training courses on a regular<br />

basis, whilst Rob and Arran are always absorbing new ideas to help improve their business.<br />

The Company operates a very small trade counter due to its location and because around 94% of sales are delivered. Talking<br />

about the distribution industry in general Arran said: “The growth (and decline) of many smaller re-sellers and the<br />

diversification of tool merchants into the welding sector has caused pressure on profit margins. With times becoming harder<br />

for manufacturers and wholesalers there has been a removal of ‘minimum order values’ and ‘quantity discounts’ which has<br />

made very competitive pricing available to any re-seller, who previously would have had to pay a premium price, if they were<br />

allowed to even open an account. This again has affected pricing in the market place.<br />

I feel things will not get any easier in the short term but there will always be a place for professional welding distribution<br />

and we continually research and look at new opportunities.<br />

I was asked by the Editor of Welding Wo<strong>rld</strong>, were I not working in the welding industry what would I like to be doing. Well, I<br />

would like to be an extreme sports athlete (with an amazing ability to consume alcohol without affecting my fitness!). How<br />

about that!”<br />

Fowlmere would like to thank all their customers and suppliers for<br />

their continued support and assure them that they will continue to<br />

support and promote them in the most professional way. CONTACT<br />

If you would like to Ask the Expert a<br />

specific question, to be answered in the<br />

next issue of AWD’s Welding Wo<strong>rld</strong>,<br />

please email expert@airproducts.com.<br />

ASK THE EXPERT<br />

Phil Tranter, marketing manager and welding industry expert<br />

at Air Products, offers advice on shielding gas selection and the<br />

benefits it can bring for most arc welding applications.<br />

ASK THE EXPERT<br />

What is the purpose of the shielding gas?<br />

In gas shielded arc welding, the primary function of a shielding gas is to protect the molten weld<br />

metal from the potentially damaging effect of the surrounding atmosphere, and also to provide the<br />

right conditions for the arc. However, a shielding gas protects more than just the weld pool, it can<br />

also help to optimise productivity and weld quality at the same time as protecting the environment.<br />

How do I decide which is the best shielding gas to use?<br />

When selecting the right shielding gas for a particular application, it is important to consider the type<br />

of weld metal being used (mild steel, stainless, aluminium or other); the welding process (MIG/MAG,<br />

TIG or other); the metal transfer mode (short arc, pulsed or spray arc) and the thickness of the material<br />

and surface conditions.<br />

The most commonly used shielding gases are inert gases such as Argon and Helium. Being inert,<br />

these gases remove air from the process and prevent oxidisation, which could damage the weld.<br />

These gases are used for a wide range of in MIG/MAG and TIG welding applications.<br />

Active gases, such as Oxygen, Carbon Dioxide, Hydrogen and Nitorgen, are sometimes used to<br />

improve weld quality or to otherwise benefit the efficiency of the welding process.<br />

How many gas mixtures are there and how are they used?<br />

There are many gas mixtures used as shielding gases (too many to mention). The most common are<br />

listed below:<br />

● Argon (TIG & MIG)<br />

● Argon + CO2 + O2 (MAG)<br />

● Helium (TIG & MIG)<br />

● CO2 (MAG or CO2 welding)<br />

● Argon + CO2 (MAG)<br />

● Argon + O2 (MAG)<br />

● Argon + He (TIG & MIG)<br />

● Argon + He + CO2 (MAG)<br />

● Argon + H2 (TIG)<br />

● Argon + CO2 + H2 (MAG)<br />

To help process managers and welders to select the right gas for the job, Air Products has developed<br />

its MAXX® range of shielding gases, based on the most commonly used mixtures for specific<br />

applications.<br />

When would it be appropriate to add oxygen and / or carbon dioxide to the shielding gas mixture<br />

and how much should be added?<br />

The addition of 1 – 5% oxygen and/or 3 to 25% carbon dioxide to argon or argon/ helium mixtures<br />

produces a noticeable improvement in arc stability and reduces the tendency for undercut and risk<br />

of insufficient penetration. Adding an active gas to the inert base gas, is what changes the process<br />

from MIG (Metal Inert Gas) to MAG (Metal Active Gas).<br />

The optimum amount of oxygen and / or carbon dioxide to be added to the inert gas depends on the<br />

surface condition of the workpiece, the joint geometry, the welding position or technique and the<br />

base metal composition. Generally, 2% oxygen and/or 8 to 10% carbon dioxide is considered a good<br />

compromise to cover a broad range of variables.<br />

JON MILLS<br />

Interview with Jon Mills Mills – Metalworking Sculptor<br />

Has your family always been involved in metalworking?<br />

My grandfather was a Birmingham jeweller and also ran a metal<br />

pressings business. My father & uncles went into the metal pressings<br />

business and heat treatment, so metalworking was always around.<br />

What made you decide to work and live in Brighton?<br />

I was born in Birmingham, and did a Design Degree in<br />

Wolverhampton. I then spent 2 years as the resident blacksmith<br />

at Bewdley Museum, Worcestershire, before wanting to get<br />

closer to London and the art gallery scene. I had contacts in<br />

Brighton so that is why I came here.<br />

Q<br />

Where did you learn to weld?<br />

I am self-taught, but it’s only very general MIG welding; I remain in<br />

awe of the many types of welding practices that go on out there.<br />

I have a 3-phase Murex Tradesmig 293 (with 1mm liner) and a<br />

Tradesmig 165 with 0.6mm liner, both using Air Liquide Argon/CO2<br />

gas plus a Hypotherm Powermax 30 plasma cutter and my local<br />

supplier is Eltham Welding in Portslade.<br />

What materials are you generally working with?<br />

Mostly mild steel and some stainless as well as cor-ten steel ranging<br />

from 1mm – 15mm plate sections. 3mm – 25mm round bar and 3-<br />

10mm flat bar.<br />

What other metalworking equipment do you use in your<br />

workshops?<br />

My grandfather was a Birmingham jeweller and also ran a metal<br />

pressings business. My father & uncles went into the metal<br />

pressings business and heat treatment, so metalworking was<br />

always around.<br />

Q<br />

What made you decide to become a sculptor<br />

in metal?<br />

I still find it hard to think of myself as a sculptor.<br />

I realised very early on at college that manipulating steel<br />

and making things gave me a real buzz – it must be in<br />

the blood. It’s a form of expression - reacting to the wo<strong>rld</strong><br />

around me makes me want to make my ‘version’ of it,<br />

but it’s not quite ‘art’ and its not quite ‘blacksmithing’.<br />

Do you mainly work with metals?<br />

I never use any other material; My style doesn’t require high precision. I might attempt<br />

to make an exact form, but sometimes it’s not what I imagined and sometimes it’s<br />

different and better than I imagined. A happy accident is not something you can<br />

specify – it just comes about through experimenting with ideas; metalworking allows<br />

me to add/weld a bit more here and there, chop a bit off, weld & grind a bit more etc<br />

I’m not sure I’d get away with it in the same way if I was a woodworker.<br />

Q<br />

Q<br />

How important is welding in your work?<br />

I couldn’t achieve anything if I couldn’t weld. I<br />

use it for shaping and building up shapes as well<br />

as surface decoration. The latter might be a<br />

“spatter” all over the surface to emulate a<br />

corroded or ‘barnacled’ lost anchor (I am sure<br />

professional welders would throw their hands up in<br />

horror but I love doing it!) I really like welding and<br />

some days I’ll be doing it for hours at a time and<br />

getting a bit cheesed off, it’s soon forgotten when<br />

I’m dreaming up the next piece.<br />

Is the life size 2-dimensional locomotive<br />

you are working on, the largest project<br />

you have undertaken?<br />

It’s the biggest project all in one piece – although<br />

I have worked on bridges (right) and railngs/gates<br />

that are taller & longer . The train has taken about<br />

3 months to fabricate, but I first proposed it 4<br />

years ago – the planning permissions/ consents<br />

etc and all the bureaucracy has been ongoing in<br />

the time in between..


Q<br />

Q<br />

What do you consider to be the most important<br />

project you have ever undertaken and why?<br />

I couldn’t say really – many jobs have been important for<br />

different reasons – one of my old favourites is a giant chandelier<br />

for Wolverhampton Museum & Art Gallery – not only because I<br />

really like it, but its in my old stamping ground! A large balcony<br />

for a Tourist Information Centre in Caerphilly (1995) was the one<br />

of the first,so in retrospect, that became a ladder rung in my<br />

career. The Dyfi Bridge in Machynlleth was my largest project<br />

with contractual implications and moments when I thought I’d<br />

lost everything, so it becomes one of the jobs you feel proud to<br />

have survived.<br />

Where can the readers of Welding Wo<strong>rld</strong> go to see your art?<br />

I have work all over the country – it best to check out my website.<br />

Q<br />

JON MILLS<br />

Can you tell me something more about your<br />

locomotive project?<br />

I have written a ‘diary’ of its fabrication which can be<br />

seen at www.metaljons.wordpress.com<br />

In many ways this has been the perfect commission – I<br />

love transport heritage and am a big fan & collector of<br />

railway and highways memorabilia. The train fits<br />

perfectly in my workshop (if I take its chimney off) and<br />

I’m happy to keep it all intact for as long as I can. Soon<br />

it will have to be disassembled and packed onto pallets<br />

for shot-blasting, zinc spraying & powder coating. It is<br />

going to sited on a disused railway bridge in Brighton –<br />

close to the site of the locomotive works and marshalling<br />

yards that used to dominate the area. It will be powder<br />

coated in different shades of grey black & white, in order<br />

to emulate the Victorian etching that I have used to<br />

scale it off. (I knew the driving wheel was 6’ diameter &<br />

scaled everything accordingly).<br />

<br />

The Metal Inert Gas welding process<br />

( (MIG (<br />

welding)<br />

Metal inert gas (MIG) welding was first patented in the USA in 1949 for<br />

welding aluminium. The arc and weld pool formed using a bare wire<br />

electrode was protected by helium gas, readily available at that time.<br />

From about 1952 the process became popular in the UK for welding<br />

aluminium using argon as the shielding gas, and for carbon steels<br />

using CO 2 . CO 2 and argon-CO 2 mixtures are known as metal active gas<br />

(MAG) processes. MIG is an attractive alternative to MMA, offering high<br />

deposition rates and high productivity.<br />

Process characteristics<br />

MIG is similar to MMA in that heat for welding is produced by forming<br />

an arc between a metal electrode and the workpiece; the electrode<br />

melts to form the weld bead.<br />

The main differences are that the metal electrode is a small diameter<br />

wire fed from a spool and an externally supplied shielding gas is<br />

necessary. As the wire is continuously fed, the process is often referred<br />

to as semi-automatic welding.<br />

Metal transfer mode<br />

The manner, or mode, in which the metal transfers from the electrode<br />

to the weld pool largely determines the operating features of the<br />

process. There are three principal metal transfer modes:<br />

<br />

Short<br />

<br />

circuiting<br />

Droplet<br />

<br />

/ spray<br />

Pulsed<br />

<br />

<br />

Short-circuiting and pulsed metal transfer are used for low current<br />

operation while spray metal transfer is only used with high welding<br />

TWI<br />

<br />

<br />

currents. In short-circuiting or ‘dip’ transfer, the molten metal forming<br />

on the tip of the wire is transferred by the wire dipping into the weld<br />

pool. This is achieved by setting a low voltage; for a 1.2mm diameter<br />

wire, arc voltage varies from about 17V (100A) to 22V (200A).<br />

Care in setting the voltage and the inductance in relation to the wire<br />

feed speed is essential to minimise spatter. Inductance is used to<br />

control the surge in current which occurs when the wire dips into the<br />

weld pool.<br />

For droplet or spray transfer, a much higher voltage is necessary to<br />

ensure that the wire does not make contact i.e.short-circuit, with the<br />

weld pool; for a 1.2mm diameter wire, the arc voltage varies from<br />

approximately 27V (250A) to 35V (400A).<br />

The molten metal at the tip of the wire transfers to the weld pool in the<br />

form of a spray of small droplets (about the diameter of the wire and<br />

smaller). However, there is a minimum current level, threshold, below<br />

which droplets are not forcibly projected across the arc.


If an open arc technique is attempted much below the threshold<br />

current level, the low arc forces would be insufficient to prevent large<br />

droplets forming at the tip of the wire.<br />

These droplets would transfer erratically across the arc under normal<br />

gravitational forces. The pulsed mode was developed as a means of<br />

stabilising the open arc at low current levels i.e. below the threshold<br />

level, to avoid short-circuiting and spatter.<br />

Metal transfer is achieved by applying pulses of current, each<br />

pulse having sufficient force to detach a droplet. Synergic pulsed<br />

MIG refers to a special type of controller which enables the<br />

power source to be tuned (pulse parameters) for the wire<br />

composition and diameter, and the pulse frequency to be<br />

set according to the wire feed speed.<br />

•<br />

Shielding gas<br />

In addition to general shielding<br />

of the arc and the weld pool,<br />

the shielding gas performs<br />

a number of important<br />

functions:<br />

forms the arc plasma<br />

stabilises the arc roots on the<br />

material surface<br />

ensures smooth transfer of molten droplets<br />

from the wire to the weld pool<br />

Thus, the shielding gas will have a substantial effect on the<br />

stability of the arc and metal transfer and the behaviour of the<br />

AWD LEADS<br />

FUME DEBATE<br />

The AWD is leading the debate on safer and environmentally friendly best practice in the<br />

fabrication industry by actively working on behalf of its member companies with the Health<br />

and Safety Executive (HSE).<br />

AWD are members of the HSE welding partnership group, which is part of a long term project<br />

that aims to raise awareness of the risks of exposure to dust, gases, fumes and vapours in<br />

the workplace and to get employers and employees to think about the way they work and<br />

whether they can be doing more to protect themselves<br />

Welding is one of the activities considered to put workers at the highest risk of exposure, to<br />

potentially harmful fumes along with work in quarries, foundries construction, carpentry and<br />

stonemasonry. Continued exposure can lead to long latency disease, respiratory ill health<br />

and even death.<br />

The partnership group has set up a discussion group which has agreed to focus on - the<br />

respiratory hazards in the welding and thermal cutting environment.<br />

This group will give advice and guidance on how to reduce the risks of respiratory disease<br />

by: . Talking to and working with those involved in the welding industry.<br />

. Raising awareness and improving workers knowledge of the risk of<br />

exposure to welding fume.<br />

. Promoting the correct use of the control measures used in high risk tasks.<br />

. Changing perceptions, attitudes and behaviours to health and safety<br />

. Encourage good working practices.<br />

PEDs-Personal Electronic Devices are an essential part of our business tool kit now. Consequently power is<br />

made available for plug in on trains, planes, airports and service stations. On planes the power socket is below<br />

the seat and supplies on average an adequate 80 watts.<br />

Popular PEDs include the sought -after iPads & iPhones which are<br />

reliable, fast and with hundreds of Apps, are exceedingly versatile.<br />

Emailing, texting, mobile phoning and web browsing via Wi-Fi and G3<br />

dongles extend the scope of flexible working whilst on the move. The<br />

office is now able to travel with us on the same journey. With high car<br />

fuel costs, slow motorway journeys and difficult parking- this flexible<br />

sales and marking support using PEDs is ever more cost effective.<br />

The rapid growth of the popular touch-screen iPad usage has been a<br />

severe challenge to Acer and other laptop suppliers, whose sales have<br />

rapidly declined. The iPad is also the death knell of underperforming<br />

10” netbooks, which have never really been popular.<br />

Tablet computers such as the iPad, ebook -electronic book reader and<br />

smart phone all constitute the post PC era. The 10”-Netbook has quickly<br />

been superseded by the faster and simpler-to use iPad tablet. There<br />

are 65,000 applications available from the Apps Store to enhance<br />

performance and utility of iPad tables. With longer life batteries, lightweight<br />

construction, and enhanced performance these are now the<br />

new business computers. There are no moving parts since storage is<br />

solid state, making the devices more rugged and faster. So for email,<br />

browsing, database logging and communicating, tablets have become<br />

vital business accessories. All of the writer’s colleagues use iPhones<br />

and iPad tablets.<br />

We are all part of the second major internet revolution where smart<br />

‘phones and tablet computers with 24 hour fast connections and<br />

unlimited data sourcing and communication access provide resources<br />

that were unthought-of just a few years ago. See www.ipsos-mori.com<br />

Dynamics of Sales & Marketing<br />

The fact that one in three high street shops have closed in many towns,<br />

shows the folly of out-of-touch town councils not providing affordable<br />

and convenient parking or making the town centres attractive. This has<br />

led retail shoppers to trade by web services and to visit distant plazas.<br />

Similarly, our customers will trade elsewhere unless we shine like<br />

beacons in the dross. It demonstrates the dynamics of sales and<br />

marketing and how we all must adjust our business practices to<br />

survive.<br />

Recent AWD AGM, exhibition and week-end networking<br />

activities at the magnificent & ancient Crewe Hall<br />

AWD has evolved its structure and services to an impressive level and<br />

the trade association is an even more significant asset to its<br />

membership. This was a valuable and creative week-end exhibition<br />

and set of top professional meetings well attended by keen and<br />

enthusiastic members. The spectrum of welding industry services and<br />

products on offer through the membership is ultra modern and far<br />

ranging. The leaderships’ volunteer directors & executive together with<br />

the very capable Sovereign Services make an impressive team and the<br />

AWD continues to be a significant and professional benefit to its<br />

membership. Do visit the new AWD website, www.awd.org.uk and do<br />

consider being an active part of this important Trade Association.<br />

Check all of the valuable website links. A talk from a senior technical<br />

director of the BCGA- British Compressed Gas Association about gas<br />

cylinders, especially acetylene in fire situations was very informative.<br />

Strong members make a strong organisation. Your trade association is<br />

very dynamic and focused and it helps to underpin the businesses that<br />

are part of the metal joining and engineering industry.<br />

WELL-BEING AND BEING VALUED<br />

Many businesses have programmes of mentoring and coaching and<br />

in-work teaching of their staff. This promotes well-being and a sense<br />

of being valued as well as improving efficiency, enthusiasm and<br />

product and service knowledge. It is another way to stay as a market<br />

leader. See Clutterbuck Associates. to be continued in next issue...


Sifbronze was established in 1925 and is one of the last companies who<br />

continue to manufacture welding consumables here in the UK.<br />

In February 2008 they became a wholly owned company within the WWS<br />

Group and now feature as part of the combined WELDABILITY SIF product range.<br />

The company has kindly offered to provide a series of technical advice documents for the welding sales<br />

engineer and AWD members, following the traditional SIFTIPS format which was originally started in 1932.<br />

Welding Copper and Brass<br />

SIF TIPS<br />

Copper<br />

Pure copper has characteristics of high thermal and electrical conductivity and, because the metal requires about six times more<br />

O<br />

heat (melting point is 1,083 C) for fusion welding than steel, particular care must be taken during welding and brazing.<br />

Tough pitch copper, which includes most varieties of high conductivity copper, contains up to 0.5% oxygen (cuprous oxide) and is<br />

not suitable for fusion welding since it has a tendency to embrittlement and cracking, though it can be brazed.<br />

Deoxidised copper, where the oxygen has been removed during manufacture by the use of deoxidising agents, can be fusion<br />

welded.<br />

For MIG and TIG welding, It will be necessary to preheat workpiece if it is over 6mm thick. The usual shielding gas is argon, but<br />

with thicker material an argon/helium mixture can beneficially increase the arc temperature. Consumables to be used are SIFMIG<br />

985 and Sifsilcopper No 985, although Sifsilcopper No 7 can be used for TIG welding sheet up to 3mm thick.<br />

O<br />

Gas welding of copper, such as whiskey stills, tanks etc, requires the parts to be preheated to 600 C and slowly cooled on<br />

completion of the joint. Sifsilcopper No 7 together with Sifsilcopper flux will produce a joint with excellent colour match.<br />

Copper is not generally joined using arc welding electrodes. But in circumstances where there is no other welding equipment other<br />

than a transformer, Hilco Bronsil proves ideal.<br />

Brass<br />

Brass is a generic term covering a wide range of copper alloys containing additions of zinc. All brasses, which includes Gilding<br />

Metal, can be silver soldered, MIG and TIG welded successfully. However, the addition of lead for free cutting brass and in<br />

gunmetal (LG1 & LG2) causes porosity and fume problems with gas shielded arc welding. Phosphor Bronze, copper/tin alloys such<br />

as PB2, can be readily brazed or welded.<br />

Gas welding of brass is not recommended as the zinc will tend to vaporise causing fumes (zinc oxide) and porosity. However, PB2<br />

phosphor bronze can be joined with oxy-acetylene and Sifphosphor However, BronzeSIFMIG No 8, as328 sometimes and 968used or Sifalbronze by sculptors. No 32 and<br />

S<br />

For MIG and TIG welding a shielding gas of argon or argon/carbon dioxide mixture is used. If it is felt necessary to use preheat,<br />

O<br />

this must be limited to less than 80 C, otherwise the structure of the brass may become altered.<br />

The choice of filler wire or rod will depend on the composition of the alloy being joined. As a general comment, SIFMIG 8 or<br />

Sifphosphor Bronze No8 is recommended as first consideration. However, SIFMIG 328 and 968 or Sifalbronze No 32 and<br />

Sifsilcopper No 968 may also be suitable. If colour match with brass is important, Sifphosphor Bronze No 82 is recommended<br />
