In this study, influences of the welding process parameters on the Submerged Arc welding were investigated. The Welding Arc Voltage, Welding Current and Welding Speed are chosen as welding process parameters. With the help of above welding process parameter we analyzed the effective welding time for SAW. This paper has analyzed in Minitab 17 software and application of Taguchi technique is used for determining the optimal process parameters for SAW process. This paper includes a analysis and study of various process control variables and important weld bead quality parameters in SAW of structural steel (IS: 2062). Mathematical models were developed for the submerged arc welding of structural steel plate's thickness of 6 mm using steel electrodes which diameter is 3.15 mm. In this analysis three factors namely welding current, welding voltage and welding speed, were considered. Accordingly, a suitable orthogonal array was selected and experiments were conducted in Minitab 17 software. After conducting the experiments the welding time measured and Signal to Noise ratio was calculated. With the help of graph and table, optimum parameter values were obtained.
