【 摘 要 】

The friction stir spot welding (FSSW) method has four welding parameters: the welding tool rotational speed, tool plunge rate, tool plunge depth, the dwell time and tool retract delay. The effects of these welding parameters on joint formation and weld strength of polypropylene friction stir spot of welds were investigated. The effects of welding parameters on welding joint formation were determined by metallographic studies. The strength of welds were determined by the lap-shear test. From the experiments, it was found that the tool plunge rate had no effect on FSSW of polypropylene sheets. The effects of other important welding parameters were clearly discovered.
