GAS METAL ARC welding (GMAW) is a process that melts and joins metals by heating them with an arc established between a continuously fed filler wire electrode and the metals. The process is used with shielding from an externally supplied gas and without the application of pressure. The American Welding Society refers to the process Gas Metal Arc Welding process to cover arc lengths of electrode and the feeding of the wire are automatically controlled. inert as well as active shield gasses. GMAW is basically a semi-automatic process, in which the Taguchi Technique is used to plan the experiments. The Taguchi method has become an influential tool for improving output during research and development. Taguchi strongly recommends for multiple runs, is to use the signal-to-noise (S/N) ratio for the same steps in the analysis. In this research work of Gas Metal Arc Welding (GMAW) show the effect of Current (A), Voltage (V), Gas Flow rate (Ltr/min) and on weld depth of ST-37 low carbon alloy steel material. In this Experiment we done Experiment by using L9 orthogonal Array to find out weld depth and also perform confirmatory Experiment to find out optimal run set of current, voltage speed and gas flow rate.
