In this present investigation, an effort has been made to evaluate the mechanical properties of AA6082 and AA7075 dissimilar aluminum alloys were joints fabricated by the Friction stir welding process (FSW). The effects of FSW process parameters such as tool revolving speed, welding speed, tool pin profiles, and axial load also investigated. Three different FSW tool pin profiles are used in this investigation like straight cylindrical, tapered, and taper threaded. The different tool speeds are 1000 rpm, 1300 rpm, and 1500 rpm. The welding speeds are utilized for this investigation is 20 mm/min, 40 mm/min, and 60 mm/min. The unvarying axial load 2kN is used in this work. The Friction stir welding process is a solid-state joining process. This method was most suitable for combined two dissimilar alloys of AA6082-AA7075. This experimental investigation was successfully done with the help of FSW process parameters. The mechanical properties and quality of the weld joints were observed after one by material testings. The material testing like as tensile and hardness test. It is used to determine the process parameters and their performance measure with the minimum variation. The optimization process was done with the help of FSW process parameters. In this context, the L9 Orthogonal array was used in the optimization process. After the end of the experimental investigation, the results indicate the massive tensile strength value is gained by a straight cylindrical pin profiled tool at a rotational speed of 1300 rpm and the welding speed is 60 mm/min. The hardness of the weld specimen is increased with the decreasing of tool revolving speed is 1000 rpm, as well as the traveling speed, which is 20 mm/min which obtained by a tapered pin profile tool. The results indicate tool pin profile plays a vital role in getting the quality of the weld joints.
