Friction-stir welding (FSW) is a solid-state joining process and used to join light alloy
metals, which finds various industrial applications in aerospace, automotive and ship building,
etc. Obtaining the required range of the parameters in friction-stir welding is essential for
ensuring defect free and high strength welded joints. This paper presents the various process
parameters used to find the mechanical and micro structural properties of friction stir welded
