Abstract

The transmission of ultrasound vibrations during welding leads to changes in the welding zone. The microstructure has a significantly reduced width of the dendritic zone than in the reference specimen.The effects of applying ultrasonic vibrations in welding of AMg4 aluminum alloy are studied. The experimental studies in the considered conditions allowed finding the optimal amplitude of vibrations (9 –10 µm). When ultrasound is applied to the molten pool, the liquid metal is subject to sound pressure, cavitation, and acoustic flows, which affects the crystallization parameters. The comparison of the microstructure of the welding zone shows a significantly reduced dendritic segregation when vibrations are applied. The weld joint obtained in the selected conditions has an increased strength and high plasticity.
