    Abstract :

    Friction stir welding is a solid state welding process where in two materials are joined without melting the material. The process is well suited for non ferrous materials such as aluminum, copper, magnesium, zinc etc. It is an effective technique for joining dissimilar metal and alloys and finds its application in various fields such as aerospace and automotive industries. In this attempt is made to join aluminum alloy AA 7075 T651 and AA 6061 T6 condition by friction stir welding technique under different process parameters such as tool rotation speed (750 rpm to 1250 rpm), welding speed (90 mm/min to 110 min) and using five different tools pin profiles –threaded cylindrical (TC), triangular profile (TP), conical profile (CP), square profile (SP) and hexagonal profile (HP). The outcome of the experimentation indicated that square tool pin profile and hexagonal tool pin profile at the tool rotation speed of 1250 rpm and the welding speed of 110 mm/min respectively yielded good quality welds in contrast to other tool pin profiles.
