Aluminum alloy finds its applications in various sectors of engineering. This paper discusses the investigation of mechanical characteristics of buttweld joints of aluminium alloy AA6063 along with AA5083. An experiment was conducted for different tool rotational speeds of 600 rpm, 800 rpm and 1000 rpm. Specifications of friction stir welding machine were 4 kN axial load and welding speed of 40 mm/min. Friction stir welded (FSW) joints of higher tensile strength, lower flexural strength and lower impact strength with maximum hardness, for the work piece fabricated at 1000 rpm using a high speed steel tool with a cylindrical profile was observed. Better understanding of the effect of tool rotational speed and mechanical properties was illustrated through the experimental result.
