Abstract: The micro structure and mechanical properties of AISI 316L/317L austenitic stainless steels with in conel 825 alloy were investigated in this work. Two types of filler materials 316L and ERNiCrMo-3 were used to obtain dissimilar weldments using TIG welding. The comparative evaluation initially studied on cutting parameters using unconventional machining process (hereby Water jet machining is considered for cutting process) and impact test is carried on all machined specimens. The impact test results for all specimens exhibits ductile fracture. A detailed micro structural observation was made on all dissimilar joints using SEM analysis. At last it was concluded that ERNiCrMo-3 filler material was the best choice for the joint AISI 317L austenitic stainless steel and Inconel 825 alloy.
