The aim of this paper is to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 for use in oil-refining industries. The welds were produced using four types of filler materials; nickel-based alloys designated as Inconel 82, A, 617, and 310 SS. The interfaces and heat-affected zones were characterized by optical and scanning electron microscopy. Interfaces on the two sides...
