Abstract : The effect of welding parameters (rotation speed and welding speed) on the mechanical properties of 3003-H12 aluminum alloy joints produced by friction stir welding. The mechanical performances of the joints were evaluated using tensile tests and the relationships between welding parameters and joint performances were investigated. The weld strength increased with increasing the welding speed or decreasing the rotation speed. The location of tensile fractures of the joints is base metal at welding parameter combinations of 1070 rpm and 40 mm/min or 2140 rpm and 224 mm/min. All other joints were failed at heat affected zone. The yield and ultimate tensile strengths of the joints decreased almost linearly with increasing rotation speed at a constant welding speed, while these strengths of the joints increased almost linearly with increasing welding speed at a constant rotation speed. But, a significant correlation could not be established between welding parameters and elongation of the joints. However, the elongation values of FSW joints is relatively lower at higher rotation speed or lower welding speed.
