Abstract：
As a kind of metal material with excellent machining pertormance,good thermal conductivity and light weight,aluminum alloy has been widely used in the industrial field.Cold metal transition welding technology(CMT),as a low heat input and no spatter welding technology,is very suitable for additive manufacturing of aluminum alloy.Aluminum alloy CMT technology has become a research hotspot in additive manufacturing technology.Based on the review of the research achievements of domestic and foreign scholars in recent years in the aspects of weld bead formation,microstructure and porosity defects of aluminum alloy CMT technology,the future development direction of CMT technology was prospected.
