In this study, an attempt was made to study the impact of process parameters of FSW on the mechanical properties of the FS welded AA6063. Properties like tensile strength, and hardness of the FSW joints were studied. Aluminium 6063 alloy is widely used in visible architectural applications such as door frames, window frames, shop fittings, irrigation tubing, sign frames and roofs. Aluminium 6063 alloy generally is hard to weld using conventional fusion welding processes. With development of Friction Stir Welding process (FSW) producing weld joint in aluminium, 6063 alloys become very easy compared to conventional fusion welding processes. In FSW, the rotating welding tool motion instigate frictional heating and severe plastic deformation and metal joining process is done in solid state. The weld obtained from FSW of AA6063 shows good mechanical properties and is defect free. Friction-stir welds don’t show defects like porosity, alloy segregation and hot cracking, which were present in conventional fusion welds. Welds with good surface finish are produced during FSW process. In this study, the changes in mechanical properties of weld zone are compared with that of the parental metal. Process parameters such as welding speed, tool rotational speed and tool tilt angle plays major roles in the joint characteristics. The focus of this study is on the optimization of all these parameters. From investigation it is found that the joint made from the FSW yielded superior tensile properties and impact strength when tool rotational speed is 1100rpm and feed rate is 0.9mm/sec.
