Abstract

It has been previously shown that it is possible to produce friction stir spot welds (FSSW) in thin (1 mm thick) aluminium sheet, when using a tool without a probe, which has the significant advantage of not leaving a keyhole in the weld. The aim of this paper was to investigate the effect of a post-weld paint-bake thermal cycle on the performance and precipitation behaviour of FSSW joints produced using a pinless tool, in the heat-treatable Al automotive alloy AA6111-T4, with rapid, industrially relevant, weld cycle times. It has been demonstrated that strong joints could be obtained within
