Metal Inert Gas welding (MIG) process is an important welding operation for joining ferrous and non ferrous metals. The MIG input welding parameters are the most important factors affecting the quality of the welding and weld quality is strongly characterized by weld bead geometry. This paper presents the effect of welding parameters like welding current, welding voltage, welding speed on penetration depth of AISI 1020 steel during welding. A plan of experiments based on Taguchi technique has been used to plan the experiment, acquire the data and to optimize the welding parameters as well as the process. Finally the conformations tests have been carried out to get the difference between the predicated values with the experimental values to find the effectiveness in the analysis of penetration.
