Abstract : In this study, Friction stir welding of Al 6061T-6 plate with accepted strength is studied with the help of preheating heat source of the AL6061 T-6 plate. Al6061 T-6 plate is preheated to 175ᵒ C, 200ᵒ C and 225ᵒ C before welding process. In two sides of Al plates preheating of friction stir welding joints is welded throughout without any un-welded zone resulting from smooth material flow by equally distributed temperature. Different preheating temperature are considered at the time of welding to simulate defect repair in the joint. Preheating welding process was developed for high strength fine grain structure of Al 6061 T-6. Preheating improves mechanical properties such as tensile strength, residual stress, bending strength, and hardness. Preheating in friction stir welding helps to improve welding speed, penetration depth, heat affected zone. The ultimate tensile strength of Al6061 T-6 plates with preheating is found higher than friction stir welding. This study includes input parameters such as tool rotational speeds in rpm (1000, 1200, 1400) tool geometry (straight cylindrical, tri angle, taper straight tri flute) and preheating temperatures (175, 200,225). The analyses of tensile strength, hardness and bending strength of the welding is carried out in this research. It has been observed by experimental analysis that preheating of material in friction stir welding can reduce heat generation between the rotating tool and the work-piece caused by friction. Keywords- Preheating, Friction Stir Welding, Tensile Strength, Bending, Hardness, Microstructure, RSM.
