Abstract: Today’s world diverts toward the light weight and high strength material at very fast rate. Consequently, aluminum alloy replaces steel structure at so many places in industries as well as in common applications. Due to that quality fabrication of aluminum alloys is essential. But non-conventional welding processes is not more efficient to join aluminum alloy. Therefore, novel green friction stir welding technology is used in the present work. Friction stir welding technology is sub-part of solid-state welding processes because it joins the metal parts before the temperature of weld zone cross the melting point with the application of axial pressure. To fulfil the objective of quality and sound welding of aluminum, effect of six different shoulder geometries are investigated in the present work. By using six non-consumable rotating FSW tools, 5 mm thick 6082 – T6 aluminum alloy plates are being welded at different tool rotation speed (600, 800 & 1000 RPM) and tool travel speed (35, 45 & 55). To check the quality of weld, tensile test and micro-hardness test are performed. From those experimental results, it is concluded that shoulder geometry of tool – 3 gave sound and quality weld with 240.42 MPa strength and 60 HV hardness.
