Abstract	Friction stir welding is a solid state welding process for joining metallic alloys. It has emerged as an alternative technology used for high strength alloys that are difficult to join with conventional techniques. The applications of FSW Process are found in several industries such as aerospace, rail, automotive and marine industries for joining Aluminum, magnesium and copper alloys. The FSW Process parameters such as rotational speed, welding speed, tool pin profile, tilt angle, plunge speed, axial force play vital role in the analysis of weld quality deciding joint strength. AA6082 aluminum alloy (A1- mg-Si) has widely used in fabrication of light weight structures. An attempt has been made to investigate the effect of different welding speeds and rotational speeds on the weld quality of AA6082 aluminum alloy. Cylindrical taper pin profile is used for tool pin profile in this research. The quality of the weld is well and no defect is found using this tool. Consequently, the obtained results explained the variation of stress as a function of strain and the effect of different welding speeds and Rotational speeds on ultimate tensile strength & elongation. The friction stir welded plates of AA6082 with the cylindrical pin profile reaches the ultimate tensile strength of 38.5% of base metal and 13% of elongation of base metal.
