Abstract
Metal Inert Gas (MIG) welding is one of the most commonly used welding process for joining different grades and alloys of steel. Its productivity and quality depends upon many factors like arc voltage, current, weld speed and heat generated during welding. There have been many studies performed on impact of welding parameters on mechanical strength during MIG welding. In this particular study, an attempt has been made to investigate the effect of varying welding current with constant voltage on the impact strength of the weld bead of similar and different material. The objective of this is to design a V- joint and evaluate the strength of the similar and dissimilar metal pieces on different current and constant voltage conditions. The materials used in this study are mild steel and stainless steel. The method used for the impact testing is IZOD test.
