We are fabricating a vessel from 1 1/4" SA516-70 and our Sub arc proceure uses a Lincoln EM12K electrode which our customer claims is not suitable for PWHT. They did not give a reason. Does anyone know why this electrode is not suitable or which type of sub arc wire would be more suitable. The procedure must meet the same tensile, elongation and impacts as the parent metal. I have contacted Lincoln about this and they are not very helpful.
