Welding consumables Welding consumables shall comply with the following Indian Standards as appropriate : 15:814 Covered Electrodes for Metal Arc Welding of structural (<strong>Part</strong> 1) steel for welding other than sheets IS:814 For welding sheets (Pan 2) IS: 1278 Filler rods and wires for gas welding IS: 1395 Low and medium alloy Steel covered electrodes for manual Metal Arc Welding 1S:3613 Acceptance Tests for wire flux combinations for submerged arc welding of structural steel 15:7280 Bare wire electrodes for gas shielded arc welding of structural steel 15:6419 Welding rods and bare electrodes for gas shielded arc welding of structural steel IS:6560 Molybdenum and chromium-molybdenum low alloy steel welding rods and bare electrodes for gas shielded arc welding 1903.3. In aggressive environment, corrosion resistant steel can be used. These are low-alloyed steels containing a total of 1 per cent - 2 per cent alloys, in particular, copper, chromium, nickel and phosphorous. 1903.4. Paints All materials for paints and enamels shall conform to the requirements specified on the drawings or other special provisions laid down by the Engineer. The type of paints which can be used shall be as follows: a) Ordinary i.e. paints based on drying oils, alkyd resin, modified alkyd resin, phenolic varnish epoxy b) Chemical Resistant - one pack type (ready for use) and two pack type (mixed before use). c) Vinyl d) Chlorinated rubber e) Bituminous f) Epoxy g) Polyurethane h) Zinc rich Unless otherwise specified, paints shall conform to the relevant IS specifications. The paints which have been tested for the following qualities as per specifications given in the relevant IS codes only shall be used : · Weight test (weight for 10 litre of paint, thoroughly mixed) · Drying time · Consistency · Dry thickness and rate of consumption. 1904. FABRICATION 1904.1. General
All work shall be in accordance with the drawings and as per these specifications with care being taken that all parts of an assembly fit accurately together. All members shall carry mark number and item number and, if required, serial number. Unless specifically required under the contract, corresponding parts interchangeable, but the parts shall be match marked as required under Clause 1904.7. need not be Templates, jigs and other appliances used for ensuring the accuracy of the work shall be of mild steel; where specially required, these shall be bushed with hard steel. All measurements shall be made by means of steel tape or other device properly calibrated. Where bridge materials have been used as templates for drilling, these shall be inspected and passed by the Engineer before they are used in the finished structure. All structural steel members and parts shall have straight edges and blunt surfaces. If necessary, they shall be straightened or flattened by pressure unless they are required to be of curvilinear forms. They shall also be free from twist. Pressure applied for straightening or flattening shall be such as would not injure the materials. Hammering shall not be permitted. Adjacent surfaces or edges shall be in close contact or at uniform distance throughout. The Contractor shall submit his programme of work to the Engineer for his approval at least 15 days before the commencement of fabrication. This programme shall include the proposed system of identification and erection marks together with complete details of fabrication and welding procedures. The Contractor shall prepare shop drawings for fabricating any member and obtain approval of the Engineer before the start of work. Complete information regarding the location, type, size and extent of all welds shall be clearly shown on the shop drawings. These drawings shall distinguish between shop and field welds. 1904.2. Preparation of Edges and Ends All structural steel -parts, where required, shall be sheared, cropped, sawn or flame cut and ground accurately to the required dimension and shape. End/edge planning and cutting shall be done by any one of the following prescribed methods or left as rolled : a) Shearing, cropping, sawing, machining, machine flame culling. b) Hand flame cutting with subsequent grinding to a smooth edge. c) Sheared edges of plate not more than 16 mm thick with subsequent grinding to smooth profile, which are for secondary use such as stiffeners and gussets. If ends of stiffeners are required to be fitted, they shall be ground, so that the maximum gap over 60 per cent of the contact area does not exceed 0.25 mm. Where flame cutting or shearing is used, at least one of the following requirements shall be satisfied. a) The cm edge is not subjected to applied stress. b) The edge is incorporated in weld. c) The hardness of cut edge does not exceed 350 HV30. d) The material is removed from edge to the extent of 2 mm or minimum necessary, so that the hardness is less than 3SO HV 30. e) Edge is suitably heat treated by approved method to the satisfaction of the Engineer and shown that cracks had not developed by dye penetrant or magnetic particle test. f) Thickness of plate is less than 40 mm for machine flame cutting for materials conforming to IS:226 and IS:2062. The requirement of hardness below 350 HV 30 of flame out edges should be specified by the Engineer. Wherever specified by the Engineer, the flame cut edges shall be ground or machined over and above the requirement (a) to (f). Where machining for edge preparation in bull joint is specified, the ends shall be machined after the members have been fabricated.
