The Effect of Welding Speed on Mg/Al Dissimilar Stirring Brazing

Abstract:

In this study, 2024 Al alloy and AZ31B Mg alloy were brazing with mechanical stirring. The effects of brazing speed on microstructure and shear strength were investigated. The results show that oxide films on Al base metal surface broken completely at lower brazing speed. The continuous IMCs layer was broken into thinner one and blocky IMCs distribution in filler metal more evenly at lower brazing speed. The shear strength value near Al and Mg interface up to 53.1Mpa and 41.5Mpa respectively.
