Abstracts: In this research work of Gas Metal Arc Welding(GMAW) show the effect of Current(A),Voltage(V),Gas Flow rate(L/Min) and Speed(M/Min) on Ultimate Tensile Strength(UTS) of st-37 low alloy steel material, In this Experiment we done Experiment by using L9 orthogonal Array to find out UTS and also perform confirmatory Experiment to find out optimal run set of current,voltage,speed and gas flow rate.
