Mechanism of weld formation during very-high-power ultrasonic additive manufacturing of Al alloy 6061
TL;DR: In this paper, the microstructures of Al alloy 6061 subjected to very high-power ultrasonic additive manufacturing were systematically examined to understand the underlying ultrasonic welding mechanism, and it was found that the weld interface between the metal tapes consisted of fine, equiaxed grains resulting from recrystallization, which was driven by simple shear deformation along the ultrasonically vibrating direction of the tape surface.
