Abstract: Welding has been the essence of the joining processes in various industrial and domestic applications. Friction Stir Welding has emerged as a potential solid-state welding process and has been used to weld two dissimilar Aluminum alloys AA 5083 O and AA 6082 T651. Generation of an empirical model for prior prediction of tensile properties from four prominent factors of Friction Stir Welding has been done. Four factors selected are tool rotation speed, tool transverse speed, tool tilt angle and square-shaped pin size. Tensile properties have been optimized using multivariable optimization. The relative impact of various factors on the tensile properties has been analyzed. Friction Stir Welding has been performed based on Response Surface Methodology and the design matrix was generated using Central composite rotatable design which includes five levels with 31 runs. The efficacy of the empirical models has been tested with Analysis of Variance and models generated were found accurate to predict the responses up to 95%. The response surfaces and contour plots of the input and response variables were generated and analyzed. The confirmatory run for the optimum values was performed with a percentage error of less than 3 percent. This paper may be useful in various industrial applications and an enhanced understanding of Friction Stir Welding.
