The Effect of Friction Stir Welding Process Parameters on the Butt Joint Strength of 5083 and 6061 Aluminum Alloys

Abstract

This journal discusses the process parameters of friction stir welding (FSW) for joining aluminum 5083 and aluminum 6061. The welding process was conducted to identify the optimal parameters for achieving high-quality joints. Based on the study's findings, the welding parameters of a tool rotational speed of 1400 rpm, a travel speed of 30 mm/s, and a tool tilt angle of 1° were identified as the best. Various tests, properties mechanical and microstructural evaluations, were conducted to assess the quality of the joints. The results indicated that the best tensile strength achieved was 180.45 MPa, corresponding to an efficiency of 78%, while the hardness value reached 65 Hv. Furthermore, the welding process under these parameters facilitated the refinement of grain size in the Weld Nugget (WN) zone, enhancing the bonding area between the two materials. This is attributed to the ability of FSW to break coarse grains into finer grains, leading to improved microstructural uniformity and consistent grain size due to the optimized process parameters.
