OPTIMASI KUALITAS HASIL PENGELASAN FRICTION STIR WELDING (FSW) SAMBUNGAN SIMILAR PADUAN ALUMINIUM AA 6061
Abstract
Friction Stir Welding (FSW) is a technique of material connection in solid state conditions and is widely used toconnect aluminum alloys in aerospace, shipping, automotive, defense and more applications in other sector. FSWwelding results can produce better mechanical properties in the welding zone compared to other conventionalwelding techniques. FSW experiments were conducted using a vertical milling machine with AA 6061 alloymaterial. The main objective of this study was to determine the optimum operating conditions in the FSW butt jointsof aluminum alloy material AA 6061. Rotation speed and welding speed were taken as process parameters. Analysisof variance (ANOVA) through software design of expert is used to reveal the effect of different welding parameterson ultimate tensile strength and hardness to obtain optimum parameters. The optimum result is predicted that theultimate tensile strength can be reached 192.129 MPa and the hardness value is 66.818 HBReferences
