Aluminium 6061 alloy is commonly used in the aircraft structures, such as wings and fuselages, more commonly in homebuilt aircraft than commercial or military aircraft. Aluminium 6061 alloy generally shows low weldability when welded using traditional fusion welding process. With development of Friction Stir Welding process (FSW) producing weld joint in aluminium 6061 alloys become very easy as compared to conventional processes. In FSW, the welding tool motion induces frictional heating and severe plastic deformation and metal joining process is done in solid state. A defect free weld with good mechanical properties in aluminium alloy 6061 can be obtained using FSW process. Unlike in traditional fusion welding, friction stir welds doesn’t shows problems like porosity alloy segregation and hot cracking. Welds produced with good surface finish during FSW process. In this paper, an attempt was made to investigate the impact of process parameters of FSW on the mechanical properties of the weld zone. The tensile strength, microstructure, hardness of the FSW joints were investigated. The changes of mechanical properties are compared with the parental metal. The welding parameters such as tool rotational speed and welding speed plays a major role in deciding the joint characteristics. This paper focuses on optimization of all these parameters. From this investigation it was found that the joint made from the FSW yielded superior tensile properties and impact strength when tool rotational speed is 1200rpm and feed rate is 0.9mm/sec.
