A framework for friction stir multi-spot welding for thermoplastics.

ABSTRACT: Friction stir spot welding (FSSW) has shown promising potential for joining sheets and other geometries of metals as well as polymers. For thermoplastic materials, especially carbon black reinforced high-density polyethylene (HDPE-CB), the FSSW technique has shown promising results. However, in the published literature, most of the FSSW studies on thermoplastic materials have focused on single-spot joints. The current paper aims to investigate and develop a framework for multi-spot based FSSW joints. Based on the study, it is evident that the strength of the weld increases with the number of weld spots, and the weld direction plays a crucial role in determining weld performance. The double-side weld configuration of T4 weld spots achieved the maximum peak load of 5207 N. Additionally, edge
