Optimization of friction welding using response surface method and Taguchi

Abstract

Welding process affect to the reducing tensile strength value in the weld joint. Improvement to weld joint performance is still studied such as friction welding. This study discussed optimization from welding parameters with Response Surface Method and Taguchi. Based on ANOVA results, that RSM and Taguchi method could be used to optimize the welding parameter. Welding parameter of friction welding could join SS304 with the highest tensile strength 766 pascal. Weld join optimize was 766.5 Pascal when welded with 920 rpm of rotation speed, 9 mm for diameter, and joining time was 2 sec. RSM recommended optimize could be achieved when tensile strength was 624 pascal, rotation speed was 556 rpm, joining time was 0.45 sec, and diameter of specimen 9 mm. Taguchi method could optimize when rotation speed 1466 rpm, diameter specimen 9 mm, and joining time 0.32 sec.
