In this investigation an attempt has been made to study the experimental comparison of friction stir welding process two (AA6082-T6 & AA7075-T6) dissimilar aluminium alloy joints. Most commonly used method for welding of aluminium alloy is TIG welding process. TIG welding process produces the sound joints but the newly developed method friction stir welding process gives better joints than TIG welding process. Of the natural aging times studied, the stir zone of all welds showed the highest kinetics of micro-hardness and strength recovery. Its effect increased considerably in the heat input per unit length decreased.
