Effect of zinc interlayer on ultrasonic spot welded aluminum-to-copper joints
TL;DR: In this paper, the effect of the Zn interlayer on the micro-structural and mechanical properties of weld joints was analyzed using X-ray spectroscopy and diffraction scans, and it was determined that welds with a Zninterlayer placed in-between the faying surfaces of the base metals formed a composite-like eutectic structure of Al and Al 2 Cu at the center and Al-Zn and CuZn 5 at the edges of the welded joint.

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.
