Research On Welding Technology And Properties Of Aluminum Alloy And Dissimilar Metals

This paper summarized the characteristics of welding technology between aluminum alloy and dissimilar metal. The welding technology and properties of different metals between aluminum alloy and steel, magnesium and copper were described in detail. The influences of welding parameters and metal composition on the microstructure and properties of welded joints were analyzed. In the future, it is necessary to strengthen the research on the welding of aluminum alloy, ultra-high strength steel, titanium and other high-end metals. New welding methods, new improved welding technology, adding suitable alloy elements and so on are needed to carry out for in-depth theoretical and practical research.
