Effect of process parameters on friction stir spot welding (FSSW) of 5052 Al alloy has been evaluated. A plunge type FSSW machine was used for this study. Sheet thicknesses of 1 and 1.6mm were used. The tool rotation rate was varied between 1000 and 3000 rpm. The tool plunge rate and dwell time was varied to give weld cycle of 1-4 seconds. Shear tests were performed in 2 sheet and 3 sheet configurations to determine the influence of processing parameters on the mechanical properties of lap joint FSSWs. Higher joint strengths were observed at lower tool rotation rates.
