Welding and repair of stainless steel and nickel-base alloys used in high temperature service present many challenges. High temperature property requirements and service environment influence weld filler metal selection. Weld filler metal ferrite and use of fully austenitic welding materials contribute additional unique situations. Repairs and dissimilar welding also offer significant challenges. Each of these areas will be discussed and examples presented to illustrate and assist in resolving or preventing many welding related issues encountered in high temperature service.
