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. The current work aims to study the effects of parameters in gas metal arc welding of AISI 1020 material. 10 mm thick AISI 1020 material plates are used as work material to be welded by gas metal arc welding process Detailed experiments are designed and performed on the basis of orthogonal array (OA) and welding strength measured and analyzed using trend graphs. An optimum combination of process parameters, finds out by Taguchi method. Optimization result has been used for identifying the most significant parameter effect on welding strength. I have studied the effect of various process parameters are voltage, Welding current, wire feed rate and welding speed of MIG Welding and the output parameter is tensile strength and microstructure. The aim of this work is the effect of microstructure on tensile strength of low carbon welded steel using inert gas welding.

Keywords- MIG Welding, Microstructure, Tensile Strength, Low Carbon Welded Steel.
