Welding Technology is a vital manufacturing process used to join metal alloys. Friction stir welding (FSW) is a solid-state welding technique in which metal is heated to plasticized state due to the friction and stirring action of the non-consumable tool over the surface of the base metals, resulting in sound weld. In the present work, influence of various process parameters on dissimilar welding of AA 6061 T6 and AA7075 T651aluminium alloys is investigated in order to improve the mechanical strength properties. Conical and cylindrical tool pin profiles are chosen to perform butt welding. The process parameters considered for the study to determine the ultimate tensile strength (UTS) and elongation of the six welded joints are tool geometry, rotational spindle speed of about 600,800 and 1000 RPM and feed rate of about 30,45,60 mm/min respectively. Finite Element Analysis, parametric model with base weld plates and the tool is performed using ABAQUS. It is observed that irrespective of the process parameters cylindrical tool rendered the better tensile and elongation property in contrast to the conical tool.
