Dear Experts,
-- How can I weld overlay on Pipe ID & OD, by qualifying welder on a plate as per below code requirements.
(c) The essential variables of QW-350 and QW-360 shall apply for welders and welding operators, respectively, except there is no limit on the maximum thickness of corrosion‐resistant overlay that may be applied in production.When specified as essential variables, the limitations of position and diameter qualified for groove welds shall apply to overlay welds, except the limitations on diameter qualified shall apply only to welds deposited in the circumferential direction.
Warm Regards
Imran khan
