چکیده
Friction stir spot welding is an emerging spot-welding technology that offers opportunities for joining a wide range of materials with minimum energy consumption. To increase productivity, the present work addresses production challenges and aims to find solutions lap-welding multiple ultrathin sheets maximum productivity. Two convex tools different edge radii were used weld four AA5754-H111 alloy each 0.3 mm thickness. understand influence tool geometries process parameters, coefficient friction (CoF), microstructure mechanical properties obtained Vickers microhardness test small punch analysed. A scanning acoustic microscope was assess quality. It found radius from 15 22.5 reduced dwell time by factor three. Samples welded specific seen have no delamination improved due longer stirring time. The rotational speed be most influential parameter in governing shape, CoF, microstructure, efficiency. Low speeds caused 14.4% 12.8% improvement joint efficiency compared high both this investigation.
