DOCUMENT TITLE:

Upon acceptance of fit-ups by the QC inspector, the Fabrication Supervisor shall organize to get the joints welded by qualified welders. The welding shall be done by proper sequence so as to minimize distortion. Welding shall be carried out in compliance with all requirements requirement s specified in AWSD1.1 or BS EN1011. EN1011. All shop welding shall be performed in an area protected protecte d from adverse weather conditions (rain, wind) and air-born dust and sand. Parts to be welded shall be carefully prepared and be firmly held before welding to avoid, as far as possible, warping, buckling and residual stresses. All welded seams shall be continuous. Visual examination for all categories of weld shall reveal no cracks. Discontinuous weld shall not be permitted. Welding, including including details details and and drawings, drawings, procedures, qualification of personnel, personnel, consumables, workmanship, quality testing and inspection, shall comply with the approved AFC drawings, WPS and ITP. The Non-Destructive Non-Destruct ive testing of welds shall be as per approved ITP. Weld Defects Defects like Undercutting Undercutting beyond beyond acceptable acceptable limits, limits, surface porosity, and and crack-like discontinuities shall be removed to sound metal and repaired. Weld profiles shall be as per approved WPS. Prior to painting, all sharp corners, burrs (including bolt hole burrs), weld spatter, slag, weld flux, loose mill scale and other foreign matter shall be removed.

PAINTING All the welded/Fabricated welded/Fabricated steel Structures on clearance clearance of NDT requirements shall be painted as per approved blasting and painting procedure – JPF3-02-MS-162- Work Method Statement for painting of Steel Structures and Piperack. For details refer to the method of statement for blasting and painting for further details.
