Friction Stir Spot Welding Development

Friction stir spot welding (FSSW) has emerged as a solid-state joining technique that addresses many limitations of conventional spot welding, particularly for aluminum alloys and dissimilar material combinations. Rather than melting materials, FSSW uses a rotating tool to generate frictional heat and mechanically mix materials at the joint interface. This process avoids solidification defects associated with fusion welding while producing joints with exceptional mechanical properties.

The 点焊机組裝 for friction stir applications differs significantly from resistance systems, incorporating:
