ABSTRACT In present days Alloy of aluminum is widely used due to its versatility especially in automotive industry. Casting makes most of the components but some may require welding too. These components are loaded statically and dynamically as per application. Due to these reason corresponding strength needed to be insured for the product having welded joint. This paper unveiled the influence of welding parameters on tensile strength of AM-40 (EN AW 5083) aluminum alloy material during welding. A Set of experiments on MIG Welding Set up based on Taguchi technique has been used. An analysis of variance (ANOVA) accompanied with regression analysis and orthogonal array of size L9, is employed to study the characteristics of welding for a material & optimizes the welding parameters. The result computed is in form of percentage contribution factor from individual parameter, by which optimal parameters are identified for maximum tensile strength. From this study, it is observed that welding current and welding Voltage are major parameters, which influence on the tensile strength of welded joint.
