Friction stir welding (FSW) is a ‘new solid-state joining process’ which is multifaceted, ecologically friendly and power capable. Some of the leading companies have been adapted this process for the manufacturing of automotive, locomotive, shipping and aerospace. In this study, the friction stir welding (FSW) method is used to connect the AA6061-T6 alloy plates and enhance the process parameters. Research is underway to analyze the various process parameters on the welded joint's quality impact. The different process parameters consequence, such as axial force, traverse speed, tool rotational speed, shoulder diameter, incline angle, and instrument geometry have been optimized by using the Taguchi technique.
