In the proposed work, two different aluminium alloys such as Al 6061 and Al 6063 of same family was selected to study the mechanical properties of the joint prepared by Friction Stir Welding. The experiments were conducted by changing the spindle speed in three different levels by maintaining the other parameters unvarying. Welded workpieces were tested for its tensile strength and micro structure in order to understand the behavior of the welding process. The results revealed that the tensile strength is increased initially when the spindle speed increases and decreased beyond the certain level. Microstructural analysis showed that, in stir zone grain refinement was happened due to which mechanical properties were improved.

Keywords- Friction Stir Welding, Dissimilar Welding, Tool Rotational Speed, Microstructure.
