Effect of Metallurgical Fundamentals and Welding Processes on Joining of Dissimilar Steels

Abstract

The dissimilar materials welding is characterized by several metallurgical characteristics which do not arise in similar materials welding. Service life of mixed joint strongly depends on manufacturing and operating conditions. In this study, welding of different materials will be investigated in a way that up-hill diffusion processes, hot cracking, dilution percentage, thermal characteristics of the material and welding procedure. Micro analyses of different material’s welding and metallurgical problems will be examined. The result of this study will allow us to explain potential joining mechanism for dissimilar steels.
