Abstract
Achieving good welding quality is one of the major challenges in gas metal arc welding. Welding processes parameters significantly affects the quality of welding and needs to be optimized to ensure quality weld. The principal processes parameters affecting the weld quality are welding current, welding voltage, welding speed, and gas flow rate. Taguchi technique and ANOVA is an efficient method for optimizing the quality and performance output of manufacturing processes. Accordingly, Taguchi and ANOVA has been employed to optimize the process parameters. In addition, a comparison of the strengths of the various welded joints obtained by the gas metal arc welding Process has been presented. Welding voltage turns out to be the most important parameter of tensile strength and hardness.
