Additive manufacturing technology is an important component of manufacturing information, digitalization and intelligence, and arc additive technology has better application advantages in aluminum alloy forming. The advantages and limitations of different additive manufacturing technologies are compared and analyzed from the aspects of metal additive manufacturing technology classification, development history, standard specification and technology principle. In particular, the arc additive technology, represented by cold metal transition technology, is introduced, and the advantages and limitations of the arc additive technology itself and its advantages of application to the integrated manufacturing of aluminum alloy structural parts are discussed. The research and development of domestic and international arc additive technology for aluminum alloys are reviewed in terms of forming process, porosity defects, toughening technology, etc. The current research work and main problems encountered in the direction of arc additive manufacturing for aluminum alloys are introduced, the toughening methods and effects of arc additive manufacturing samples for aluminum alloys are analyzed, and relevant excellent cases at home and abroad are introduced.
