Dear Expert,
During a site observation, a subcontractor's carbon steel shell (EH36, thickness 40 mm) was found re-rolled due to ovality after 100% of the NDT(UT&MPI) long seam welds. Many stresses come and grain boundaries are stretched after rolling such a thick joint.Any experts please advise.
Standard - DNV-OSC -401
Construction specifications - AWS D1.1
Thanks & Regards
Rajesh
