Introduction to the SAW technicalhandbookThis technical handbook gives detailedinformation of the extensive range of ESABconsumables for joining materials with thesubmerged arc welding process, along withgeneral information associated with thisprocess. Consumables for cladding andhardfacing are described in otherdocuments available from ESAB. Thishandbook consists of three main sections: The flux selection tables enable the correctflux to be chosen for various practicalwelding situations: page 5 and AWS, page 10-12 page 13Page 15 gives a theoretical background forthe choice of the most suitable flux/wirecombination.The product data pages give acomprehensive description of fluxcharacteristics and application areas, and allrelevant data on the flux and flux/wirecombinations, including approvals.Technical HandbookChemical composition, mechanicalproperties and other data are typical, unlessotherwise stated. Only the main approvalauthorities are listed.An extended overview of mechanicalproperties and a full list of approvals foreach product may be given in the productdata sheets (PDS) available from ESAB.Certain products, with particularly beneficialproperties, are discussed in detail onseparate pages following the product datapage of the flux in question.Submerged Arc WeldingThe general information pages discuss theSAW process in detail - including its processvariants, packaging and handling, ESAB asa global producer of SAW flux and wiresand classification standards.FLUXES AND WIRES FOR JOINING NON AND LOW-ALLOYEDSTEELS, STAINLESS STEELS AND NICKEL-BASE ALLOYS4

How to choose the right flux-wirecombinationStainless steelWhen joining stainless steel the wire shall be of the samechemical composition as the base material or over-alloyed. Forsimilar wires a low-C variant should be chosen over aNb-stabilized as long as it is permitted by the customer contract.OK Flux 10.93 is often the correct flux, but alternative fluxes arechosen if the ferrite content needs to be changed slightly or if therisk of hot cracking needs to be reduced.Ni-alloys and 9% Ni-steelsNi-alloys are welded with OK Flux 10.90. The wire shall be of thesame chemical composition as the base material. 9% Ni-steelsare also welded with OK Flux 10.90 and various welding wirese.g. OK Autrod 19.81, 19.82, or 19.83.Non and low alloyed steelsFluxes can be chosen for particular applications, such as lowimpurity levels in creep resistant steels, pipemills, welding on rustor mill scale, narrow gap welding or low temperature toughness.The correct flux for these applications can be chosen with theflux characteristics selection chart on page 9. For some lowalloyed steels, e.g. creep resistant steels, the chemistry of the fillerwire shall match the chemistry of the base material. Thecorresponding fluxes are selected with the table on page 13. Forother applications, the best flux-wire-combination is identified bycriteria such as running characteristics, specified toughness andstrength or joint preparation.Flux basicityBasicity is calculated from a flux’s chemical components,independently of the wire. Higher basicity gives better impactvalues, but reduces features such as welding speed, parameterenvelope or fine rippling of the weld bead. It is therefore beneficialto choose the lowest possible flux basicity at the specifiedtoughness. From the various basicity formulas the following is themost generally accepted one:The formula shows that low basicity fluxes contain moremultiple oxides. A certain amount of atomically bonded oxygenis favourable for the weld microstructure. In all weld metal,however, this favourable level is already exceeded, even withhigh basic fluxes. Typical oxygen levels are:Low basicity flux> 750 ppm High basic flux< 300 ppmIn highly diluted welds with low oxygen parent material,however, the oxygen level can fall below the favourable level.The different basicity and oxygen levels lead to large differencesin all weld metal toughness with the same wire, Autrod 12.22:Low basicity flux OK Flux 10.81 >47J/ +20°CNeutral basicity flux OK Flux 10.78 >47J/ -20°CBasic flux OK Flux 10.71 >47J/ -40°CHigh basic flux OK Flux 10.62 >47J/ -50°CStrengthThe strength of non-alloyed weld metal is mainly achieved withC, Mn and Si. A number of wires are available for variousstrength levels, using the same flux. Generally, the weldstrength should match the base metal. The flux also influencesthe strength level, because each flux alloys different amounts ofMn and Si to the weld metal.Welding jointDilution also affects the Mn and Si content, making mechanicalproperties of actual joints differ largely from all weld metal. Amulti-run V-joint consists of approximately 90% weld metal withmechanical properties similar to all weld metal. In a square buttjoint, however, only 20% is weld metal resulting in mechanicalproperties that are largely influenced by the parent materialchemistry (see page 65 - 67).Based on this formula fluxes are divided into the following groups:B < 0.9 low basicity flux B > 2.0 high basic fluxApprovalsApproval society requirements are taken into account whenspecifying a flux/wire combination.

OK Flux 10.47 & OK Tubrod 15.24Sbasic cored wire - no re-baking offlux and high productivityThe use of a basic cored wire,instead of a solid wire, allowsthe weld metal toughnessproperties to be engineeredthrough the cored wire ratherthan through a highly basic flux.This opens the way to the useof a lower basicity fused fluxwith a very low moisture contentand a moisture re-absorptionrate close to zero, which isundoubtedly, the biggestadvantage for applicationswhere low weld metal hydrogencontents are crucial. Thisenables the flux to be usedwithout the costly, and timeconsumingprocedure ofre-baking.As with gas-shielded coredwires, the metal sheathconducts the current, insteadof the complete wire crosssection resulting in a highercurrent density. This highercurrent density is converted toincreased deposition rates and,therefore, productivity.Weldability characteristics areexcellent; comparable to thebest basic agglomerated fluxesavailable on the market. Slagrelease is very good even in thebottom of tight butt joints nearthe root area, enabling the jointangle to be reduced.Due to the glass nature of theflux, the grain strength issignificantly higher than that ofthe fully basic agglomeratedfluxes. This results in lessbreakdown and hence noproblems with “dusting” andtherefore all round improvedrecycling.Mechanical values fulfil mostoffshore requirements: Diffusible Hydrogen (ml/100g)10.0Toughness (J)8.06.04.02..00.00 2 4 6 8 10 12 14DaysOK-Tubrod 15.24S / OK10.47 -AWS All-weld metal toughness-70 -50 -30 -10 10 30Temperature ( 0 C)AWS All-weld metal procedureDeposition rate (kg/h)2018161412108642Climatic Exposure ResultsDiffusible hydrogen exposure testsOK Flux 10.47 with Tubrod 15.24S 4.0mm600 amps, 30mm Stickout, 30VExposure@19g H 2 0 m -3 (25 0 C 80%RH)25020015010050015.00S 2.4mm15.00S 3mm15.00S 4mm12.20 2.5mm12.20 3mm12.20 4mm0300 350 400 450 500 550 600 650 700 750 800 850 900 950 1000Current (A)4.0mm3.0mm2.4mmDeposition rate comparison OK Tubrod 15.00S andOK Autrod 12.20 / OK Flux 10.71.Increased deposition on 50mm plateProductivity increase of 30%Solid wire 48 runsOK Tubrod 15.24S 37 runs22

Narrow gap welding - completeESAB solution for repetitivefabrication of thick sectionsNarrow gap welding becomes attractive with heavy wallthickness sections in repetitive fabrication, e.g. thefabrication of foundation piles for the offshore and windenergy segments. ESAB provides a total solution whichincludes specialised welding equipment, weldingconsumables and automation.The main advantage of narrow gap welding is thegreatly reduced weld volume in very thick sections,which results in weld cycle time reduction. Furthermore,the one-sided butt arrangement makes it easier toavoid linear misalignments, as opposed to two-sidedjoints (X prep.).When considering this process, it must be taken intoaccount that it involves a large initial investment, as wellas the more expensive machining of narrow gap jointpreparations. These need to be fully justified by costanalysis, in which ESAB can assist.It is essential that the process operates free frominconsistencies. The side-wall wetting must be perfectin order to avoid lack of fusion in the following layer.Slag is required to be self releasing, even onpreheated high strength steels.OK Flux 10.62 meets all these criteria, and is also verysuited when low hydrogen is required to avoid coldcracking. It is an EN 760 H5 classified flux which issuited for low-temperature steels, due to its highbasicity.Effect of Configuration on Weld Joint Area - Based on 150 mm ThicknessRelative Joint Area (%)160All Joints have 5 mm landReinforcement is not included in the calculation140120Narrow gap welding can be single or tandem wire;both requiring specially designed welding heads(swords), narrow enough to fit into the jointpreparation. All heads - including types with contactjaws, flux supply, flux recovery or tactile sensors - areinsulated. This is to avoid unwanted arcing, whenthe equipment accidentally moves against the jointedges. Typical wire diameters are 3 and 4 mm. Up to350 mm thickness can be welded with the standardESAB head, but special versions are available forthicker sections.1008060402002 degree NarrowGap50 degree DY 60 degree DY 50 degree Y 60 degree YIn 150 mm material thickness, 5 mm land - reinforcement not included.29

Pressure vessels arewelded with this flux, because itcan be used for a wide range ofsteels including lowtemperature steels. Thisreduces the number of differentfluxes a customer needs tohave in stock. Wind towerproduction with platethicknesses of greater than50mm require not only excellentslag detachability, particularly inthe first run, and highdeposition rates in all followingruns, but also excellenttoughness values. Since OKFlux 10.71 offers all this it iswell established in this marketsegment. Other applications arein shipbuilding with approvals orin the production of pipes withsteels up to X70 strength level.OK Flux 10.71 can also becombined with a number ofSAW cored wires in order toincrease the productivity andthe mechanical properties ofthe weld metal.For more information view the Product Data Sheets or contact ESAB.35

OK Flux 10.72 – Toughness to -50°C– not only for wind towersOK Flux 10.72 is anagglomerated, basic flux,designed for the production ofwind towers. It combines the highdemands for multi-layer thicksection welding, using highdeposition rates with respectabletoughness values down to -50°Cwhen combined with a standardnon-alloyed SAW wire.It is used for single and multi- wireprocedures such as tandem, twinarc,tandem-twin welding andmany more, for butt and filletwelds. It works equally well on DCand AC current. The excellent slagremoval in narrow V-joints allowsthe included angle of the joint tobe reduced. OK Flux 10.72 canbe applied for unlimited platethicknesses.In wind tower production, platethicknesses of 50mm and aboveare common, generally welded slag is easily removable on the firstrun. For the remaining fillingpasses the flux needs to offer ahigh current carrying capacity, toallow for high deposition rates, forexample, 38kg/h with the tandemtwinprocess. Often toughnessvalues down to -50 0 C are requiredthroughout the thickness. Thisexcellent flux can also be utilisedin other market segments withsimilar welding requirements e.g.pressure vessels and generalconstruction welding.Classification flux Basicity index Density Grain sizeEN 760: SA AB 1 57 AC H5 1.9 ~ 1.2 kg/dm 3 0.2 - 1.6 mmSlag type Polarity Alloy transfer HydrogenAluminate-basic DC+ / AC No Si and moderately MnalloyingFlux consumptionkg flux / kg wireVoltage DC+ AC26 0.7 0.630 1.0 0.934 1.3 1.238 1.6 1.4Classification1,00,80,60,40,20,0-0,2% Si pick-upfrom flux450 A750 A% Si in wire0,05 0,10 0,15 0,20 0,25 0,30Single wire, ø 4.0 mm, DC+, 30 V, 60 cm/min1,81,41,00,60,2-0,2-0,6-1,0 5 HDM% Mn pick-upfrom flux450 A750 A% Mn in wire0,5 1,0 1,5 2,0WireWeld metalOK Autrod EN / AWS EN / AW AWS / AW AWS / PWHT12.20 S2 / EM12 S 38 5 AB S2 A5.17: F7A8-EM12 A5.17: F6P8-EM1212.22 S2Si / EM12K S 38 5 AB S2Si A5.17: F7A8-EM12K A5.17: F6P8-EM12K12.24 S2Mo; S Mo / EA2 S 46 3 AB S2Mo A5.23: F8A5-EA2-A3 A5.23: F8P5-EA2-A313.64 SZ / EG (two-run classification, see Product Data Sheet)ApprovalsABS BV DNV GL LR TÜV DB CEOK Flux 10.72 x xwith OK Autrod12.20 x x x12.22 x x x12.24 x x xTypical weld metal chemical composition (%), DC+C Si Mn Cr Ni Mo OtherWith OK Autrod12.20 0.05 0.2 1.512.22 0.05 0.3 1.512.24 0.05 0.2 1.6 0.5Typical weld metal mechanical properties, DC+ReL / Rp0.2(MPa)Rm(MPa)A4 / A5(%)CVN(J at °C)With OK Autrod -30 -46 -50 -6212.20 415 500 30 125 70 50 AW12.22 415 500 30 120 70 50 AW12.24 500 590 25 60 35 AW12.20 360 460 32 130 70 50 SR12.22 360 460 32 130 70 50 SR12.24 490 580 25 60 35 SRAW/SRRemarksFor more information view the Product Data Sheets or contact ESAB.36

OK Flux 10.72 - Wind towers,pressure vessels and generalconstructionptOK Flux 10.72 is designed for multi-run fillet and buttwelding and provides reliable low-temperature toughness at fabricators to increase productivity further with four-wire andtandem-twin arc welding. The flux is well established in windtower fabrication, but also in the manufacturing of pressurevessels, penstocks and in general fabrication.Tandem-twin – a major step forward.The development of tandem-twin SAW coincided with thedevelopment of OK Flux 10.72. The process brings weldingproductivity to new levels. It can be used for all welds with most importantly the circumferential welds that make up themajority in wind tower fabrication. OK Flux 10.72 is capableof accommodating the high deposition rate of the tandemtwinprocess. The table on this page compares thedeposition rates for various SAW techniques and shows thesuperior productivity from the tandem-twin process.Productivity can be further increased by reducing the jointincluded angle from 60 to 50°, enabled by the excellent slagdetachability in narrow joints of OK Flux 10.72. Comparing a 50° joint welded with tandem twin (19% joint volume), it canbe calculated that the arc time is almost halved (seeSvetsaren 2/2005 p.16).Comparison of deposition rates for variousSAW techniques.SAW process Wire combination Deposition rate at 100% dutycycleSingle wire 1 x 4.0 mm 12 kg/hTwin-wire 2 x 2.5 mm 15 kg/hTandem wire 2 x 4.0 mm 25 kg/hTandem-Twin 4 x 2.5 mm 38 kg/hReduction of joint cross section by reduced opening angle,using OK Flux 10.72Plate thicknessCross sectionY- joint 60°Cross sectionY- joint 50°(mm) 5mm land, no gap (mm 2 ) 5mm land, no gap (mm 2 ) (%)25 231 187 -1935 520 420 -1945 924 746 -19Reduction38

The submerged arc weldingprocessSubmerged arc welding (SAW) is amethod in which the heat required tofuse the metal is generated by an arcformed by an electric current passingbetween the electrode and the workpiece.A layer of granulated mineralmaterial known as submerged arcwelding flux covers the tip of thewelding wire, the arc, and the workpiece.There is no visible arc and nosparks, spatter or fume. The electrodemay be a solid or cored wire or a strip.SAW is normally a mechanised process.The welding current, arc voltage, andtravel speed all affect the bead shape,depth of penetration and chemicalcomposition of the deposited weldmetal. Since the operator cannotobserve the weld pool, great reliance isplaced on parameter setting andpositioning of the electrode.General scope: range between 100 and 3600 amps The welding operationWhen the apparatus is set intooperation, several things occur in quicksequence: through the hopper tube andcontinuously distributes itself over theseam a short distance ahead of thewelding zone. feed the welding wire into the joint ata controlled rate current flows between the electrodeand the work. automatically) to travel along theseam.The tremendous heat evolved by thepassage of the electric current throughthe welding zone melts the end of thewire and the adjacent edges of thework-pieces, creating a pool of moltenmetal. The submerged arc welding fluxcompletely shields the welding zonefrom contact with the atmosphere.As the welding zone moves along thejoint, the fused submerged arc weldingflux cools and hardens into a brittle,glass-like material which protects theweld until cool, then usually detachesitself completely from the weld.Benefits deep and safe penetration Limitations during welding possible Equipment – Basic PrinciplesThe high welding speeds anddeposition rates which arecharacteristic of submerged arc weldingrequire automatic control of the motorthat feeds the welding wire into theweld. No manual welder could smoothlydeposit welding wire at speedscomparable to those of a submergedarc welding machine. Nor could hemaintain the same precise control ofwelding parameters. The automaticcontrol and power supply system usedin submerged arc welding operates tomaintain a constant voltage andcurrent.Relationship of welding voltage todistance between welding wire andwork-pieceThe welding voltage is proportional tothe length of the current path betweenthe welding wire and work-piece: work-piece increases, the weldingvoltage will increase. work-piece decreases, the weldingvoltage will decrease.65

work-piece remains constant, thewelding voltage will remain constant.Rate of wire melt-off vs. rate of wirefeed If, for any short period of time, thecurrent flowing through the weldingzone melts off the wire at a faster ratethan it is being fed, the distancebetween wire and work will increase,and welding voltage will increase.Conversely, if for any short period oftime, wire is fed faster than it meltsoff, the distance between wire andwork will decrease, and weldingvoltage will decrease.A constant welding voltage can bemaintained if a control unit is usedwhich will automatically vary the rateof wire feed with change in weldingvoltage. With a constant potential powersystem the arc voltage is maintainedby the power supply. Arc current iscontrolled by the wire feed speed withincreased wire feed producingincreased current. Therefore, the wirefeed system is simplified to a constantspeed device and arc control isperformed by the power source.Controllable variablesA knowledge and control of the variablesin submerged arc welding are essential ifwelds of good quality are to beconsistently obtained. The variables are:Welding currentWelding current is the most influentialvariable. It controls the rate at whichwelding wire is burned off, the depth offusion, and the amount of base metalfused. If the current is too high, thedepth of fusion will be too great and theweld may melt through the backing. Inaddition to this, the higher heatdeveloped may excessively extend theheat-affected zone of the adjacent plate.Too high a current also means a wasteof power and a waste of welding wire inthe form of excessive reinforcement. Ifthe current is too low, there isinsufficient penetration and not enoughreinforcement.Welding voltageThis is the potential difference betweenthe tip of the welding wire and thesurface of the molten weld metal. Thewelding voltage varies with the length ofthe gap between the welding wire andthe molten weld metal. If the gapincreases, the welding voltageincreases; if the gap decreases, thewelding voltage decreases.The welding voltage has little effect on theamount of welding wire deposited; mainlythe welding current determines this. Thevoltage principally determines the shapeof the fusion zone and reinforcement.High welding voltage produces a wider,flatter, less deeply penetrated weld thanlow welding voltage.Welding speedWith any combination of weldingcurrent and voltage, the effects ofchanging the welding speed conform toa general pattern:If the welding speed is increased: weld is decreased. smaller. of undercut and insufficientreinforcement.Effect of welding current on weld profile.If the welding speed is decreased: weld is increased. larger. Effect of arc voltage on weld profile.Consequently a large weld bead canlead to a slow cooling rate and excessivegrain growth, which can have adeleterious effect on the toughness ofthe weld metal.66

If the welding speed is decreased beyond acertain point, the penetration will alsodecrease. This is because a good portion ofthe molten weld pool will be beneath thewelding wire and the pool will cushion thepenetrating force of the arc.Effect of wire extension on weld profile.Welding directionWidth and depth of welding fluxIf the granular layer is too deep, a roughweld is likely to result. The gases generatedduring welding cannot readily escape, andthe surface of the molten weld metal isirregularly distorted.If the granular layer is too shallow, thewelding zone will not be entirely submerged.Flashing and spattering will be present; theweld will have a bad appearance, and mayPulling(backhand)NeutralPushing(Forehand)be porous. An optimum depth of granularmaterial exists for any set of weldingconditions. This depth can be establishedby slowly increasing the granular materialCircumferential weldinguntil the welding action is submerged andflashing no longer occurs.Electrode extensionThe distance between the contact tip andwork-piece is normally referred to as electrodeextension or stick-out and is typically between Small offset at edges Desired offset slight reinforcementLarge offset at centre and high atedgesincreased with the use of longer extensionsdue to resistive heating of the wire. If the stickoutis too long then the wire is preheated andcan tend to wander leading to miss-alignmentalso penetration is reduced.Angle of welding headThe pulling or backhand technique givesgreater penetration and a narrower weldwith a more convex weld bead. There isincreased risk of undercut using thisWeld metal dilutiondepends on the jointpreparation.technique.

SAW variantsCored Wire Single Wire Twin WireFlux hopperWelding wireWire feed unitWelding wireFlux hopperWire feed unitPowersourcePowersourceFlux fillWelding directionFlux fillWelding directionBase materialBase materialThe use of cored wire is a very simpleand easy way to increase the depositionrate in SAW without any major changesto existing equipment. As the currentdensity determines the burn-off rate ofthe wire, the deposition rate with thecored wire is higher than that with solidwire. The powder in the core of the wirecan be used to achieve weld metalchemistry and mechanical propertiesthat may not be readily available withsolid wires. ESAB basic cored wires canbe used with fused fluxes to achieveexcellent sub-zero toughness that couldbe difficult with solid wires and fusedfluxes. This enables the nonhygroscopicnature of the fused flux to befully utilized and baking of the flux beforeuse is not necessary. (see page 22)Cored wires can be used in any of theprocess variants listed here to give extraproductivity benefits.Single wire welding is the most widelyused SAW method. The solid or diameter, although for some thin 1.6mm can be used. DC+ current is out. A smaller diameter produces ahigher deposition rate at the samecurrent, because of a higher currentdensity. The current range for a largerdiameter involves higher currents andtherefore also higher deposition rates.A smaller diameter wire produces amore deeply penetrating andnarrower weld bead.For twin-wire welding, two wires areconnected to the same power source.A standard SAW machine is equippedwith double drive rolls and contact tipssuitable for feeding two wiressimultaneously. It producesconsiderably higher deposition ratesthan the conventional single-wireprocess using large diameter wires. Itoffers up to 30% higher deposition ratesand can be used at higher currents andspeeds. Very high welding speeds canbe achieved in fillet welding, but is alsoused successfully for butt welding.Cored wires can further enhancedeposition rates.Number of Wires 1 2Number of Power Sources 1 1Wire Diameter Range (mm) 1.6 - 5.0 1.2 - 3.0Current Range (A) total 200 - 1000 400 - 1200Current Type DC+ DC+Voltage (V) per wire 25 - 38 26 - 38Max. total deposition rate solid wire (kg/h) up to 12 up to 1568

Neutral, active or alloying fluxesFluxes for submerged are weldingcan be grouped into neutral, active andalloying fluxes. Many fluxes alloy someSi and Mn to the weld metal; yet othersburn off these elements. The intensity ofthis chemical reaction depends on theflux quantity interacting with the wire.An increase in voltage/arc length willlead to an increased alloy or burn-off ofelements.Neutral fluxesIn the ESAB product range,neutral fluxes are those intended formulti-layer welding of unlimited platethickness with appropriate wires. Thealloying of elements, especially Si andMn, are carefully controlled. After thebalance for each element is met, thelevel remains consistent throughout allfollowing runs.The all weld metal chemical analysisindicates the balance point and isa good reference. For single layerapplications with neutral fluxes, theuse of wires with higher Si and Mncontents may be considered.Active fluxesActive fluxes add a significantamount of Si, acting as a deoxidiser,and Mn to the weld metal.They enhance resistance to porosity,improve bead appearance andtoughness in high dilution applications.Active fluxes are primarily used forsingle pass or multi-layer weldingwith limitation of layers.Since the balance point for Si and Mnis above normally anticipated levels,3 - 5 layers is normally the maximum.Alloy fluxesAlloy fluxes create an alloyed weldmetal, when combined with unalloyedwires. The ESAB product range offersa number of alloyed fluxes used forcladding applications. These fluxesadd C and Cr as well as Si and Mnto the weld metal. The alloying ofelements is related to the arc voltage,since this has an influence on theamount of flux being melted andtaking part in the chemical reaction. Inorder to create a specific weld metalcomposition, the arc voltage must becarefully controlled.ESAB Submerged arc joiningfluxesEach joining flux is catagorised asneutral or active in the table onpage 9.Weld metal alloyingIn the arc, chemical reactions takeplace between the molten wire andthe molten flux. They depend on thecomposition of both consumables.WorldwideWires with relatively low Mn andmoderate Si content are widely used.Most common is EM12K (OK Autrod12.22) with typically 1.0% Mn and 0.2%Si. Most fluxes alloy some Mn and Si tothe weld metal to obtain the desired Mn Mn/Si ratio of at least 2.In non-alloyed weld metals, Mn isthe main element used to increase thestrength. Si is needed for deoxidation andfluidity of the molten pool. C is burnt-offby the fluxes. A low C content isdesired for good toughness values.Only high basic fluxes (OKFlux 10.62) are neutral with regardto Si and Mn. All alloying comesfrom the wire, making the chemicalweld metal composition largelyindependent of the number ofpasses and welding parameters.High basic fluxes are generallycombined with wires with increasedMn content such as OK Autrod12.32, EH12K.Asia PacificTraditionally in Asia, wires witha high Mn and low Si content areused. These are EH14 (OK Autrod12.40) with less than 0.1% Si and2.0% Mn. In order to produce thedesired weld metal composition,appropriate fluxes burn-off Mn. Theyalloy high amounts of Si. A similaramount of C is burnt-off, as withEuropean fluxes.Suitable fluxes for multi-passwelding with OK Autrod 12.40 areOK Flux 10.61 and 10.62.Flux-wire-combinations are awell adjusted systems. Generally,an EH14 wire is not welded witha Mn-alloying flux, particularly notfor multi-pass welds, because ofalloying mismatch. For specialapplications (high dilution), however,it can be a suitable combination.70

Hydrogen in ferritic weld metalFerritic, fine grained steels,especially those with higher orhigh strength (Rel > 460 MPa), aresensitive to hydrogen induced coldcracking. Cracking can occur inthe heat affected zone (HAZ) andsometimes in weld metal, aftercooling down below 150°C. Crackingcan often be delayed several hoursafter welding. The risk of hydrogeninduced cold cracks is governed bythe 3 factors; microstructure, stressand hydrogen.HAZ and weld microstructureWith increasing base material andweld metal strength, the sensitivityfor cold cracks increases. Strengthis related to hardness, whichis determined by the chemicalcomposition (CE; carbon equivalent)and the t 8/5 cooling time (seebelow: Preheating). In order toachieve a high strength in steel andweld metal, alloying elements areintentionally added. This increasesthe CE value and sensitivity for coldcracking.StressesDuring welding, thermal stressesare added to the joint due to nonuniformtemperature distribution.In thicker plates using multi-layerwelding, these stresses increasewhich means a greater risk of coldcracks. An unfavorable design of aconstruction or an unfavorable orderof completing welding joints canfurther increase stresses.HydrogenHydrogen can be introducedinto weld metal from many differentsources, such as the surroundingatmosphere, plate contamination(cutting oil, grease, dirt, paint,coating, rust), flux and wire andcompressed air. All factors mustbe carefully controlled. For weldinghigh strength steels, fluxes with thesupplement H5 according to EN760 should be used. This meansthat a weld metal with maximum 5ml hydrogen per 100 g weld metalis produced with re-dried flux. Anincreasing hydrogen level increasesthe risk of cold cracks. Re-drying ofthe flux prior to use is recommended(see page 87).PreheatingHigh strength steels should bepreheated before welding, includingtack welding. Preheating increasesthe time the welding zone remainsabove 150°C; temperatures at whichhydrogen can diffuse away. It alsoreduces stress and eliminatesmoisture from the plate surface.Preheat temperatures are usuallybetween 80°C and 150°C. The heatinput and maximum interpasstemperature must be well controlledfor good toughness. A desired, finegrained structure is achieved byusing multi-layer techniques with thinlayers. An immediate post weld heat for at least 2 hours) further reducesthe hydrogen in the welding zone(see: EN1011-2).Austenitic weld metals are notsensitive to hydrogen cold cracking,because their face centered cubiclattice can dissolve a substantiallyhigher amount of hydrogen.ESABptH5 classlow-hydrogen weldingfluxes Hydrogen bubble initiation and propagation from grain boundary.71

Agglomerated and fused fluxesAgglomerated fluxThe main task of SAW fluxes is toprotect the arc, the molten pool and thesolidifying weld metal from the atmosphere.Moreover fluxes have the following tasks: Fluxes consist of minerals such asquartz, limestone, fluorspar, manganese andaluminum oxides. These components areobtained from natural sources, globally, andare well defined and specified. The ESABwelding fluxes are composed according tocentrally controlled formulations.Agglomerated fluxes are designedfor a wide range of applications. Also incountries where, historically, fused fluxeshave been used, more and more customersare transferring to agglomerated fluxes.Since these fluxes are hygroscopic, it isrecommended to re-dry the flux, prior touse, for hydrogen sensitive applications (seepage 87).Fused fluxesFused fluxes are manufactured bymelting all ingredients in an electrical arcfurnace. The fusion temperature is between1200 and 1400°C. After the pouring ofthe melt and solidification, the material iscrushed to grains, which are dried andsieved. Characteristically, fused flux grainsare chemically homogeneous - the closestcomparison being crushed glass.Fused fluxAgglomerated fluxesAgglomerated fluxes are manufacturedby “rolling” the components with additionof silicates. For this, the raw materials aremilled to small particles. Many of these smallparticles form a grain which contains thecorrect proportion of each component. Thegrains are dried and baked at temperaturesbetween 600°C and 850°C. Agglomeratedgrains are chemically heterogeneous.Since these fluxes have not reactedduring manufacturing, metallic deoxidants oralloying elements can be added. This is oneof the major advantages over fused fluxes,because the weld metal is more efficientlydeoxidised. As a result the toughnessvalues achieved at sub-zero-temperaturesare higher than those from fused fluxes.During welding the flux consumption islower, because the density is lower. Alsoin many applications the bead shape withagglomerated fluxes is more favorable.The grain strength of fused fluxesis higher than agglomerated fluxes.This can be beneficial when long fluxdelivery distances have to be overcomeby pneumatic transport or when therecommended addition of fresh flux to thesystem is not possible. Fused fluxes arenon-hygroscopic by nature and normally donot need to be re-dried prior to use.With high currents and low weldingspeeds, e.g. in cladding applications,some fused fluxes perform better thanagglomerated fluxes. Because re-dryingcan be avoided, fused fluxes can be abeneficial alternative to agglomerated ones.In combination with basic cored wires givinghigh toughness values, fused fluxes are evenapplied on hydrogen-crack sensitive, offshoreconstructions (see page 22).72

Cored wires for submerged arcweldingCored wires can replace solid wires inthe submerged arc welding process to givean immediate productivity benefit, withoutany major capital expenditure.achieved with a solid wire. This needs tobe considered when establishing suitableparameters for the root area of joints andalso for square edge butt joints.With cored wires the current is carriedonly by the steel sheath. This leads toan increase in the current density andsubsequently a higher wire burn-off rate.This increased burn-off can result in20-30% more weld metal being deposited,compared with the same diameter solid wireat the same current.Cored wires will produce a morefavourable, rounded bead shape than solidwires which reduces the susceptibility tocracking by reducing the depth / width ratio.Also in two-sided, two pass welds there isless chance of misalignment.Solid wireAn increased deposition rate leadsto productivity benefits, reducing costswith less flux consumption, less energyconsumption and reduced labour costs.Cored wireThere are two variants of cored wiresused in the submerged arc process.

Handling equipmentESAB wire conduit A6Turntables, inner centering device and one wayspider frame.The efficiency of welding equipment can be dramaticallyincreased by decreasing the downtime. Bulk spool typeshelp to reduce the downtime by reducing the number ofspool changes. Switching from conventional 30 kg spoolsto 1000 kg EcoCoil, the number of spool changes isreduced by a factor of 33.Low friction inlet wireguiding tubeWire guide standAdjustable brakeBulk spool types such as EcoCoil (1000 kg), One WaySpider (800 kg) and drums (280kg) must be placed onturntables for decoiling. The wire is pulled by the wirefeeder, which rotates the turntable. During the complete useof these spools, the wire keeps the same twist and can bestraightened reliably at the welding unit.All turntables are low friction, easy rotating and without amotor drive, because they are rotated by the pulling of thewelding wire. They have an adjustable brake and areelectrically isolated. This is needed, because the wire haswelding voltage and any connection to ground must bestrictly avoided.The Type 1 turntable for drums has a diameter of 680 mmand a maximum load of 450 kg. The wire pick up point isintegrated by a vertical wire guide stand and a low frictionwire guide tube, through which the wire is fed to the weldingunit. 4 plastic bolts in the turntable center the drum.Lifting yoke forMarathon PacFor the EcoCoil and One Way Spider there are 2 turntables.Both have a diameter of 1050 mm and a maximum load of1000 kg.Type 2 has a wire guide stand and a fixed wire guide tubewhich gives the recommended 20 - 30° downwards inclineto the pack which is beneficial for smooth decoiling. Aninner steel centering device (yellow) designed to fit the OneWay Spider Frame (blue) ensures that the packs sit in thecentre of the turntable. EcoCoil is placed on the One WaySpider Frame.Type 3 turntable” is the single turntable. It has beendesigned for customers who position the wire pick-up pointindividually on their welding unit or on a steel framework.Marathon Pac TM trolley and lifting yokeWires up to 2.0 mm are delivered in MarathonPac (450, 475 kg). It is pre-twisted and feedsvertically and straight. Marathon Pac needs norotation and thus can be placed directly on theshop floor or on a trolley available from ESAB.Marathon Pacs can be safely lifted with aCE-signed yoke approved for crane and forkliftwork up to 500kg.76

ESAB 100kg wire basket.For a welding machine to weld, thewire must be fed disturbance free to the packages are therefore delivered on the wirebasket spool type 28 and 31. This uniqueEurospool TM is not only layer wound, butit also flush-fits on a Europallet (Figure 1).Damage and thus time to fix problems areminimised. The wire end is safely secured tothe spool basket by resistance welding.Also the 100 kg package is deliveredon a wire basket (Figure 2). The basketkeeps the welding wire in place on thespool holder, after the transport strips arecut, securing smooth decoiling. The wireend is also fixed to the wire basket in orderto prevent the end from detaching. It will,however, be detached by a reasonablestrong force from the feeding motor. This isneeded because 100 kg packages are oftenpositioned at the end of the boom, awayfrom the welding head.spool changes. Then the cost saving begins.Advantages over heavy spools are achieved,because the wire is not spooled tightlyaround the cardboard core, due to a specialtechnology (Figure 4). In the start and stopphase the spool can slowly accelerateand stop whilst the welding wire is fed tothe welding head with a constant speed.Welding defects are thereby reduced.SAW welding wires up to 2.0 mmdiameter are also available in MarathonPac (spool type 94). The wire is pre-twistedand is fed, straight and vertically, out ofthe Marathon Pac. No decoiling stand isneeded. Dramatic time savings on spoolchanges can be achieved when transferringfrom any low-weight spool type to MarathonPac. All material is fully recyclable and easyto separate.Figure 3. EcoCoil on a turning table.In many welding set-ups, it is possible toexchange conventional 30 kg spools by bulkspool types. Spool type 33, EcoCoil with1000 kg wire, reduces the spool changesby a factor of 33 (Figure 3). Moreover thepacking material is reduced to a minimum,whilst still giving full protection frommoisture and dust during transportand storage. All materials are fullyrecyclable. Since it is a oneway-packagethere isno need for any returnlogistics.Figure 4. Spool type 33 - EcoCoil.EcoCoil fits well onthe One Way Spider frame(also used for spool type 18). The costs forthe required decoiling stand / turning tableare soon compensated by the time saving forSpool type 94 - Marathon Pac is folded flatafter use for mimimal disposal space.83

Always the most productivedelivery packagingESAB delivers fluxes in 25 kg paperbags, some types in 20 kg paper bags.Each bag has a polyethylene inlay to preventmoisture pick-up from the surroundingatmosphere. Secondary protection againstmoisture pick up is given by wrap foilingor shrink foiling each complete flux palette.The packing material is fully recyclableand therefore environmentally friendly. Themajority of the packing material is recycledas paper.The main ESAB flux types are alsoavailable in BigBags. Standard weight forBigBags is 1000 kg of welding flux. BigBagshave a well defined discharge spout whichcan be closed during the flux flow.Although it takes only about 25 secondsto empty a complete BigBag, customerscan chose to remove only a few kgs at atime. Therefore, BigBags are not only forlarge volume users. The complete BigBagis made from woven polypropylene materialwhich has an internal coating for moistureprotection to keep the flux dry. The materialis fully recyclable. Again, each palette of fluxis additionally protected against moisture bywrap foil or shrink foilFor a more robust package ESAB cansupply fluxes in steel buckets containing 20to 30 kg. Buckets are moisture tight andre-sealable, allowing the re-drying of the fluxto be avoided. They are usually for outdoorwelding or when re-drying facilities are notavailable.ESAB specifies not only its products, butalso packaging and packing materials, for allproduction units, globally. Hence we ensurethat our customers such as internationalwelding companies will always get the sameproduct in the same packaging, no matterwhich continent their manufacturing is located.86

Easy and efficient storage andhandling of fluxesEquipment for storage and re-dryingESAB fluxes, agglomerated and fused, havea guaranteed as-manufactured moisturecontent from production. This moisturecontent is controlled by internal ESABspecifications. Before transport, each palletis shrink wrapped in plastic foil. Thisprecautionary action is done in order tomaintain the as-manufactured moisturecontent for as long as possible.
