Experimental and Microstructural Analysis of TIG and MIG Welding on Dissimilar Steels

Abstract

Mild steel and stainless steels are the two utmost steels used in the automotive industries as well as in various constructional and industrial applications. Welding of these steels with lesser defects and higher strengths is the most important need of the current industries. In this paper, TIG and MIG welding is preformed between two dissimilar steels. Transitional changes happen frequently in physical and microstructural properties; therefore, this study carries out an experimental and microstructural analysis to determine the properties like hardness, impact strength, tensile strength and microstructure of the weld zone.
