Abstract
In this study, a detailed practical investigation to determine the tensile strength of a thin aluminum plate joint and to produce a good thin aluminum plate joint. The purpose of this study is to run and find the right formula of rotational speed (rpm) and travel speed (mm/min) for the friction stir welding (FSW) process on an aluminum thin plate AA5052 1.5 mm plate joint. The optimum parameters for this research are at 910 rpm rotation speed with 340 mm/min travel speed and 2° angle. The tensile strength that had been collected can achieve up to 85% of the base metal (BM). The tool geometry was design with a pin diameter of 1.4 mm, shoulder diameter of 6 mm, and length of 20 mm. The results show that FSW improves the mechanical properties of welded joints compared to other welding processes.
