Experimental Study of Friction Stir Welding on Ductility in Material AA6061-T651

Friction Stir Welding is a semi-conductor welding system used to join aluminum, and other alloy metals. This study is to determine the ductility of AA 6061 Aluminum material which has gone through the welding process with the Friction Stir Welding Technique. The test used is the Bend test using the ANOVA analysis taguchi method. Using the process parameters of tool rotation speed 765, 1208, 1907, 3022 (rpm), tool rotation speed 24, 43, 65, 90 (mm/min), tool tilt angle 2, 2.5, 3, 3.5 (°), and concave shoulder angle 2, 5, 8, 11 (°). As follows, the results of the ANOVA test on the FSW Process parameters contributed N by 34.40%, WS contributed 1.93%, TL contributed 6.76% and SBC contributed 23.56%. The results of the ANOVA test show that the FSW process parameters have a major role in contributing to the FSW process, namely Tool Rotation Speed and Welding Speed.
