Abstract: Multi-wire arc additive manufacturing technology has the advantages of low cost and high efficiency， especially high flexibility in composition design and regulation， and has become the mainstream technology for the preparation of large-scale complex metal structural parts. Multiple wires （same or different） are fed at the same time to realize in-situ alloying in the molten pool. This method provides a feasible path for the preparation of advanced metal materials with complex compositions. This paper discusses the research progress of multi-wire arc additive manufacturing in the preparation of traditional materials such as high-performance titanium alloys， aluminum alloys， and stainless steels， as well as advanced metal materials such as functionally graded materials， high-entropy alloys， and intermetallic compounds. The problems of uneven microstructure， anisotropy of mechanical properties and insufficient forming accuracy of multi-wire arc additive manufacturing components are discussed. The development directions of multi-wire arc additive manufacturing process window， multi-process coupling， and forming process monitoring and control system are proposed， which provide a theoretical basis for the improvement and development of the multi-wire arc additive manufacturing process.
