【 摘 要 】

This research emphases on friction stir welding (FSW) of 5086 aluminum alloy (AA), welded samples were prepared at different rotating speed 1500, 1700 and 1900 RPM at feeding speed of welding 60 mm/min. the mechanical properties of the joints such as the Micro-hardness and tensile strength of the joints were tested. According to experimental results, the joints mechanical properties were strongly affected by the welding parameter. The optimum results of the weld gained at 1700 RPM rotation speed and 60 mm/min weld speed and where the efficiency reaches up to 84% of the (UTS) ultimate tensile strength of the parent metal.
