Özet

Friction-stir spot welding (FSSW) is a solid-state welding process suitable for the spot joining of lightweight low-melting-point materials. The process is performed by plunging a rotating pin that creates a connection between sheets in an overlap configuration by means of frictional heat and mechanical work. In this study the tensile-shear-strength and hardness variations in the weld regions are discussed. The results obtained are compared with those derived from the application of traditional resistance spot welding (RSW). The experimental results of the study show that FSSW can be an efficient alternate process to electrical resistance spot welding.
