Weld Joint Performance of Two Dissimilar Metals by GMAW

Abstract

In present experiment stainless steel and mild steel were joined together by the process of Gas Metal Arc Welding. To check effects of the process chosen we had set parameters like wire feed rate, welding speed, gas flow rate, distance of nozzle and the inclination of the plate. Taguchi’s robust design was used for the experiment and the parameters used were changed at each stage. After obtaining a satisfactory weld we decided to check the Tensile strength of the material using an ultimate tensile machine (UTM) and to determine which parameters are the best to obtain satisfactory quality of weld.
