Deformation suppression and microstructure-property evolution of ultrasonic-assisted laser-welded 7075 aluminum alloy thin-sheet joints
The Ultrasonic-assisted laser welding was used to investigate the effect of ultrasonic input on the quality of 7075 aluminum alloy thin-sheet joints. Post-weld deformation, weld formation, microstructure, and mechanical properties were evaluated by deformation measurement, metallographic observation, tensile testing, a...
