Hardsness Testing Of MIG Welding Process For Similar And Dissimilar Materials

MIG Welding is massively used in industrial process. The major advantage of the MIG welding process is that not only its versatility but also it causes almost no loss of metals. MIG can be operated as a semiautomatic or fully automatic welding. During literature review we found that there is very less study and research work done on welding of two different metals joining together. Then we have been decided and selected material of Mild steel and Aluminium for the study and investigation of Mechanical properties. Initially, with the help of trial-and-error method, we successfully welded aluminium and mild still together using MIG Welding Process. MIG Welding setting Parameters we keep constant like voltage and current for different specimen for getting same result. We have also completed hardness testing for specimen. As a result, this study has been successfully completed with the help of MIG welding experimentation and welding joint hardness test for specimens.
