Dear Members,
 
                  We have a welded the nozzles to shell 40mm thick.As per API 650 we have done  PWHT of full assembly in the furnace.After PWHT in MPI we found some indication which is going more deeper than 4mm.Can anybody tell me whether PWHT is required to be done once again after this repair.API 650 gives requirememts only for stress relieving but not for repair.Can i apply ASME SEC VIII div 1 UCS 56 Subclause 9(F)(2) for this repair.
