Abstract

Friction Stir Spot Welding (FSSW) process was employed to produce lap spot welds of C11000 copper and aluminium alloy AA1060. The microstructures of the spot welds produced at different processing parameters were analyzed. Copper rings with different lengths were observed in all the spot welds. An Energy Dispersive Spectroscopy (EDS) mapping of a region of the keyhole and the Copper rings was conducted, results showed the presence of Copper particles in the Aluminium matrix and almost no Aluminium particles are found in the Copper rings. Furthermore, the distribution of the fine Copper fragments and particles in the zone close to the Aluminium parent material of some of the produced spot welds were seen in the Scanning Electron Microscopy (SEM) images.
