Abstract

This study deals with friction stir welding of aluminum alloy(A5083). Welding conditions were applied that revolution 2000rpm, friction pressure 25MPa, angle between stir rod section and plate 4$^{\circ}$, projection pin diameter 4mm, traverse speed 0.5mm/sec, 1.0mm/sec, 1.5mm/sec. The experimental results as follows; 1. Welding beads were superior in traverse speed 1.0mm/sec and it were formed plenty of flash in traverse speed 0.5 mm/sec. Welding beads were rough in traverse speed 1.5mm/sec. 2. The maximum tensile strength was 211MPa in traverse speed 1.0mm/sec, in this case the strength was 85% of A5083 base metal tensile strength.
