Mechanical and Microstructure Properties Evaluation of Tig Welded Dissimilar Metal Ss304-Ss316

Abstract

Different grades of stainless steel are used in the construction and manufacturing of fusion reactor and boiler parts. Experimentation, study, and optimization of TIG welding to connect dissimilar grades of stainless steel (SS 316-SS304) are the goals of this project.Variables in the work are parameters such as current. Mechanical properties such as tensile strength and microstructure properties such as scanning electron microscope (SEM) and Rockwell hardness test with varying welding current are used to evaluate the welding parameters. We study the mechanical properties and microstructure of austenitic stainless steel welds made from SS 316 and SS 304.The significance of welding parameters for mechanical properties is determined using the UTM computer. Welding is the most vital and common operation use for joining of two similar and dissimilar parts.
