Shielded Metal Arc Welding (SMAW) is the most widely used welding process in the small scale industries, because of its low cost, flexibility, portability and versatility. The SMAW welding parameters are most important factors affecting the quality, productivity and cost of welding. It is related to strength of weld. In this research work of Gas Metal Arc Welding (GMAW) show the current effect, voltage effect, arc length, welding speed and angle of welding on penetration and weld bead width on MS2062. The result effected electrode life E6013 and we find optimum parameters for optimum electrode life and penetration with least possible weld bead width. An experiment runs by automatic welding are conduct using on L27 orthogonal array for optimization of welding parameters level of current, voltage, speed, angle and electrode gap. Calculate signal to noise ratio and obtain optimum level of each input parameters and find least possible weld bead length and maximum possible penetration with best electrode life.
