| Abstract | ||||
| The aim of the present work is to optimize the welding parameters for friction stir spot welding on heat treatable AA2024 aluminium alloy/Polycarbonate and Polypropylene sheets using analysis of variance (ANOVA). The optimum welding parameters for the peak temperature of the joints were predicted, and the individual importance of each parameter on the temperature of the friction stir spot weld was evaluated by examining the analysis of variance (ANOVA) results. The optimum levels of the dwell time and tool rotational speed were found to be 6 s and 1500 rpm, respectively. The ANOVA results indicated that the dwell time has the higher statistical effect with 56.16% on the peak temperature, followed by the rotational speed and tool respectively.
