英文摘要	Sn-based and Zn-based soldering filling metals were selected, and 6063 Al alloy and AZ31B Mg alloy were welded by ultrasonic-assisted soldering in the atmosphere, and the microstructures of the solder joints soldered with the two soldering filler metals were analyzed by OM, SEM and EDS spectrum. The results indicate that when the Sn-based soldering filler metal is adopted, the joints cannot generate Mg-Al brittle intermetallic compounds, and the Al element dissolved in soldering seams exists in the joint in the form of Al-Sn-Zn and Ag (Al) phases, and when the ultrasonic action time reaches 4.5 s, the Al element is uniformly distributed in the whole soldering seam. When the Zn-based soldering filler metal is adopted, a large amount of brittle Mg/Al intermetallic compounds are generated in the joint, and the second phase of Sn particles with low-melting-point disperses at the grain boundary of the soldering seam.
