Abstracts: The Friction Stir welding is the recent development in the solid state welding, to overcome the difficulties of the fusion base welding technology. In The Aerospace, Shipbuilding Automobile & railway, the Friction Stir Welding Technique is readily use nowadays. The Friction Stir Welding Technique was invented by the team of welding institute at UK in year 1991. Initially the attempt was made to join the Aluminum (Al) & it’s Alloys, Recently the research works are going on the various composite materials, Magnesium & its alloy & also for the Stainless Steel, etc. The Friction Stir Welding Techniques (FSW) gives the best joining efficiency & mechanical properties with less or negligible defect free weld. It is also an environmental friendly process. The Aim of present work, to study the effect of various tool design & process parameter on quality of Friction Stir Welding of AA 6101 T6 alloy plate of 6mm thickness, was selected. The welding was carried out using by different tools: 1. Hexagonal pin with flat shoulder 2. Square pin with flat shoulder 3. Taper pin with flat shoulder 4. Plain cylindrical pin with flat shoulder The Objectives of this process to study & investigation of welded Aluminum (Al) Plate’s properties like Tensile Strength and Microstructure of welded Plates.
