The welding processes most widely used for the welding process for aluminum alloys are incorporated with welding defects such as poor solidification and porosity in fusion zone. It is evident that the Friction stir welding is possible for defect free welding. In this present investigation AA6082 butt friction stir welded with AA2014 to get high weld metal properties and corrosion resistance. The optimization of the process parameters to get the better mechanical and micro structural properties of dissimilar joints AA2014 and AA6082 was done by friction stir welding using design of experiments in Taguchi`s method. The considered process parameters were welding speed, tool rotation speed, tilt angle. The process parameters were optimized and ranked based on the Signal to Noise Ratio values and means. The optimized welding parameters were the tool rotational speed of 600rpm, travel Speed of 60mm/min and Tilt angle of 1°. An attempt was made to join the dissimilar aluminium plate of 6 mm thickness with conical threaded tool profile. The quality of the joint was evaluated by means of tensile strength, impact test, micro hardness, macro, microstructure and salt spray test.
