Study the Effect of Tool Rotation Speed and Welding Speed on Mechanical Properties of Welded Aluminum Alloy (Welding Through Friction Stir Process)

Friction Stir Welding (FSW) was carried out on commercially available Aluminum Alloy 6063T-6 and AA 6061 plates, with dimensions of 150×75×6 mm. in my project we have selected dissimilar materials, especially on aluminum alloy 6061 and 6063-T6, Design of experiment (DOE) was applied to determine the most important factors which influence Ultimate Tensile Strength (UTS) of AA 6063 T-6 and AA 6061 joints produced by Friction Stir Welding (FSW). Effect of two factors which include tool rotational speed, welding speed. By Taguchi method using L9 orthogonal array, the optimum of process parameters was determined. GRA analysis was carried out to determine the percentage contribution of each factor on Tensile Strength. Particular emphasis has been given to the Effect of welding speed and tool rotation speed on welded work piece and study on mechanical properties.
