Cr-Mo creep resistant steels are used specially for power tubines and pipings due to their long term creep resistant properties at elevated temperatures and pressures. Welding is commonly required to join the different structural components made of this steel. Therefore weld joints should also possess required properties at elevated temperatures, which depend on correct choice of filler material, preheat treatment, post heat treatment and welding technique used. Possible failures of weld joints and their remedies have been discussed. Various welding processes for these steels are also reviewed.

Abstract


Cr-Mo creep resistant steels are used specially for power tubines and pipings due to their long term creep resistant properties at elevated temperatures and pressures. Welding is commonly required to join the different structural components made of this steel. Therefore weld joints should also possess required properties at elevated temperatures, which depend on correct choice of filler material, preheat treatment, post heat treatment and welding technique used. Possible failures of weld joints and their remedies have been discussed. Various welding processes for these steels are also reviewed.
