In this study Metal inert gas (MIG) welding also known as Gas Metal Arc Welding (GMAW) process consists of heating, melting and solidification of parent metals and a filler material in localized fusion zone by a transient heat source to form a joint between the parent metals. A consumable electrode is used which also plays the role of conductor. MIG welding gives little loss of material and can be operated as semi as well as fully automated. We have used AISI 1020 Low carbon steel, 10mm plate thickness and single V-groove joint is used. In which input parameters for MIG welding are welding speed, voltage, gas flow rate and wire feed rate. And the output parameters are tensile strength and heat affected zone (HAZ) for quality target. I have studied design of experiment method (orthogonal array) for this work and by use of the experimental data have optimized by Taguchi method. The aim of this study is to investigate the optimization process parameters for Metal inert gas welding (MIG).
