The Effect of Tool Angles on Welding Temperature in Friction Stir Lap Welding Process on AA1100 Aluminum Sheet

Investigation of micro friction stir laps welding joints on aluminum AA1100 sheet, applying high rotation tool. This research aims to observe the effect of the tool angles on the temperature during the joining process. The parameters to be used are the traverse speed, the tilt angles during the welding process and the diameter of tool pin, the tool rotation speed of 33,000 rpm. The results of data analysis used multi variable analysis with Response Surface Methodology (RSM). There are 3 parameters (Tilt angle, Travers speed, Pin diameter) and 3 variances. Here it can be seen that the tool angle greatly affects the increase in welding temperature.
