The paper deals with the optimization of welding parameters of friction stir welding of different Aluminium alloy groups. For this purpose 5 series Aluminium alloy Al 5083 and 6 series Aluminium alloy Al 6062 were taken .Tensile Strength test and micro structure analysis under various rotating speeds and tool profiles is conducted. It is observed that the increase in tool rotation speed and the tool axial force result in increase of ultimate tensile strength (UTS) up to a maximum value. In-significant effects of the tool profile at low welding speeds are noticed. At higher speeds square tool profile achieves higher strength than that of circular tool profile.
