Abstract

Ultra-thin sheets' welding is an intricate process either by conventional or advanced techniques. In the present investigation, Micro friction stir welding (FSW) was successfully performed to join the ultra-thin (0.5 mm thick) commercial aluminum. Suitable fixture and tool were developed for the ultra-thin sheets to perform experiments. Velocity ratio of rotational speed to transvers speed was varied to obtain ultra-thin friction stir welding. The welded samples were investigated by visual examination, macro-graphs, microstructure, tensile testing with fracture surface analysis and micro hardness distribution. The results revealed that, the sound joint was achieved at the velocity ratio of 13.71. The tensile strength of 100.877 N/mm2 and elongation of 23.12% were obtained, which were 90.77% and 51.377% of the parent material respectively. Fracture surfaces after tensile testing was observed with elongated dimples indicating ductile fracture. The maximum micro hardness of 94 HV was observed in the weld zone.
