Gas metal arc welding can be defined as a fusion welding process having wide range of applications in the industry. In this process proper selection of input welding parameters are necessary in order to obtain good quality of weld with good tensile strength and increase the productivity of the process. In order to obtain a good quality of weld of high tensile strength, it is necessary to control the input welding parameters. In this research work, experiments were carried out on mild steel plates using gas metal arc welding process. Taguchi method is used to formulate the experimental design. The exhaustive survey suggests that some control factors viz. arc voltage, welding current and Root Gap. A series of experiments based on Taguchi technique has been used to acquire the data. An Orthogonal array, signal to noise (S/N) ratio are employed to investigate the welding characteristics of Mild steel of material & optimize the welding parameters. Finally the conformations tests have been carried out to and experimental and predicted values are compared.
