Friction Stir welding is a strong state joining and moderately another welding procedure that has a noteworthy points of interest contrasted with the combination welding procedure, For example, joining customarily non combination weld capable compound, being a strong state joining process it produces weld with lessened contortion and enhanced mechanical properties. The use of aluminium combination are broadly utilized as a part of various modern application, for example, send building, and car ventures because of their light weight great mechanical quality and high consumption resistance. The primary point of the venture is to enhance the device profile among the four tool profile in friction stir welding which increment the yield quality and hardness. In this venture, the principle parameters considered are warmth contribution from the device shoulder and apparatus stick. The temperature circulation investigation is done utilizing the math device programming. the four work piece are welded with the four diverse apparatus stick profile at the speed and bolster rate of 1200rpm and 1.25 mm/sec. in the wake of welding the work piece, hardness and malleable test are performed to check the quality of the work piece. Scanning electron magnifying lens is utilized to check whether any deformities and porosity in the work piece in the wake of welding.
