Abstract	This paper reveals an experimental investigation into the influence of welding process parameters of ZE41A magnesium alloy. Experiments are performed, based on Response Surface Method (RSM)- Box Benkhen design. The objective is to understand the effect of welding parameters such as arc current, gas flow rate, and filler metal diameter on the mechanical properties, particularly the hardness and tensile strength, of ZE41A magnesium alloy joints. The performances of the process are evaluated by the hardness and tensile strength of the joint. A second order polynomial regression model has been developed for these input parameters and responses. Analysis of Variance (ANOVA) has been used to test the significance of parameters and adequacy of the developed mode. The confirmation test results prove that the optimal combination of welding parameters achieved from the study improves the performance characteristics of the process.
