MIG welding techniques are widely used in industries for joining of metal pieces in an inert gas environment using a wire electrode. The wire electrode is constantly fed for producing arc and acts as filler metal for the weld pool. This study is carried out for optimization of MIG welding parameters for AISI 1020 Mild Steel. The input parameters reserved for this study are the welding voltage(V), welding current (I), welding speed(WS), and the data is collected through experimentation. The output responses such as Tensile Strength and surface roughness (SR) have been considered for analysis. Taguchi L9 design is employed to conduct the experiments, ANOVA is used for calculating the effects of input process parameters. From the experimental results, it is analyzed that welding voltage is the main affecting parameter for tensile strength while welding speed is least influencing for it and for the surface roughness, welding speed has major dominance while other parameters were less effective.
