This paper presents the optimization of welding parameter for joining mild steel 1020 using ABB metal inert gas (MIG) robot welding. Mild Steel AISI 1020 with a thickness of 6 mm was selected in this experiment. The specimens cut into size 140 mm × 130 mm × 6 mm and then welded with ABB MIG robot welding used 1.0 mm electrode wire. Three welding parameters such as welding speed, Voltage, and welding pattern, each at three levels were considered. An L9 Orthogonal Array and signal-to-noise (S/N) ratio were employed to analyse the significant and percentage of each parameter for maximum tensile strength. The results revealed that the welding pattern gave significant main effects on the highest percentage distribution (61%), followed by the Welding Speed (11%) and Voltage (3%). Further, the results indicated that the combination of optimum parameter recorded as welding speed 5.5 mm/min, 22 V for Voltage and straight pattern travel capable to offer high tensile test strength. The observed data have been interpreted, discussed and analysed by using Taguchi method.
