Combining values from the two systems may result in non-conformance with the standard. The steel shall be made by either or both basic-oxygen or electric-furnace processes. If you want to find out what’s really happening at the failure asm, I would advise removing the portion of weld that’s adjacent to the leak flush with the wall and perform a PT asrm.
