Abstract
The Friction stir spot welding technique was used to produce lap spot welds of AA1060 and C11000. Various process parameters and tool geometries were used to fabricate the welds. The microstructures of the produced spot welds produced were examined by using optical microscopy (OM) and scanning electron microscopy (SEM). The chemical analysis of the cross sections of the welds was investigated by using energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD). A good Al/Cu material mixing was observed in most of the fabricated spot welds. The presence of copper rings on both sides of the keyhole with different lengths was observed in all the spot welds. The mapping using energy dispersive spectroscopy of a region of the keyhole/copper rings and the stir zone showed the presence of copper particles in the aluminium matrix. However. Very few aluminium particles were found in the copper rings. Intermetallic compounds were found in some of the spot welds.
