摘要：

Weldability of the dissimilar weld joint between austenitic 304L(N) stainless steel (SS) and martensitic 403 SS made by gas tungsten arc welding process using ERNiCr-3 filler metal has been studied. For this study, 12 mm thick plates of these two materials were joined using a K-type weld groove joint, with the straight edge on the 403 SS side buttered using ERNiCr-3 filler wire. TWO types of weld joints were prepared-one using as-buttered 403 SS and the other one with buttered and post-weld heat-treated 403 SS plate. The joint made with the as-buttered 403 SS plate exhibits good bend ductility and toughness on the heat-affected zone (HAZ) of the 403 SS side and it is comparable with that of the buttered and post-weld heat-treated 403SS weld joint properties. Thus, buttering of the 403 SS plate enabled dissimilar welding with the 304L(N) SS plate without any post-weld heat treatment because of auto tempering of the martensite present in the 403 SS HAZ formed due to weld thermal cycle.
