Abstract
The MIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. These welding parameters are welding current, welding voltage, Gas flow rate, wire feed rate, etc. they influence weld strength, weld pool geometry of Steel material during welding. By using DOE method, the parameters can be optimize and have the best parameters combination for target quality. The analysis from DOE method can give the significance of the parameters which effect change of the quality and strength of product. A plan of experiments based on Taguchi technique will be used to acquire the data. An Orthogonal array, signal to noise (S/N) ratio and analysis of variance (ANOVA) will be employed to study the welding characteristics of material & optimize the welding parameters. The result computed will be in form of contribution from each parameter, through which optimal parameters will be identified for maximum tensile strength.
