This paper summarizes the results of test activities for the characterization of GTA welding pipes between low-alloy steel or alloy steel Gr. T22, T91 and T92 and 310HCbN stainless steel. In service condition, these dissimilar joints - for Ultra Super Critical (USC) power plant application - may be subjected to significant microstructure modifications which can affect their performance or even promote crack initiation and propagation. Through a relevant number of tests, the most significant combinations of base and filler materials were evaluated in comparative terms (using non-destructive and destructive testings) in order to evaluate - among other things - the influence of post weld heat treatment filler material and aging conditions of the welded joint.
