Process Optimization of Friction Welded Spot Aluminum Alloy Using ANOVA


The parameter of angular speed, depth of tool, and time of dwell of friction welded spot was studied on the alloy of aluminium. To do so, the impact from parameters was investigated through tensile shear test on the welded alloy and using the design of experiment (L8). ANOVA is then used to see important factors and contributions via main effects plots. It was found that angular speed of tool had a big impact on tensile shear load with 45 %, time of dwell 34 %, depth of tool 10 %. The angular speed of 1 400 rpm, time of dwell 9 s, and depth of tool 3.5 mm were the optimal parameters in this study.
