Additive manufacturing technology is a special processing technology that has developed rapidly in the past 30 years. The materials used are divided into powder and wire. Additive manufacturing technology using wire as the material has the advantages of high deposition rate, uniform composition, and high density. It has received increasingly more attention, especially for the high efficiency and rapid prototyping of large-size and complex-shaped components. Wire arc additive manufacturing has its unique advantages. The concept, connotation, and development history of arc additive manufacturing technology in foreign countries are reviewed, and the current research status of arc-based metal additive manufacturing technology is reviewed from the principles, development history, process, and practical application of arc additive manufacturing technology. It focuses on the forming system, forming material, residual stress and pores, and other defect controls of the technology, as well as the current methods of mechanical properties and process quality improvement, and the development prospects of arc additive manufacturing technology are prospected. The results show that the related research work of wire arc additive manufacturing technology is still mainly focused on the experimental research stage and has yet not gone deep into the exploration of the forming mechanism. The research work in this field should be more in-depth and systematic from the physical process of forming the molten pool system from the perspectives of stability, the organization evolution law, and performance optimization. We strive to carry out wire arc additive forming technology and theoretical research to promote the application of this technology in modern manufacturing.
增材制造技术是一种在过去30年中迅速发展的特殊加工技术。所使用的材料分为粉末和线材。以线材为材料的增材制造技术具有沉积速率高、成分均匀、密度高的优点。它受到了越来越多的关注，特别是对于大型和复杂形状部件的高效和快速成型。电弧增材制造具有其独特的优势。综述了国外电弧增材制造技术的概念、内涵和发展历程，并从电弧增材制造技术的原理、发展历程、工艺和实际应用等方面综述了电弧基金属增材制造技术的研究现状。重点介绍了该技术的成型系统、成型材料、残余应力和气孔等缺陷控制，以及目前改善力学性能和工艺质量的方法，并展望了电弧增材制造技术的发展前景。结果表明，电弧增材制造技术的相关研究工作仍主要集中在实验研究阶段，尚未深入到成型机理的探索。该领域的研究工作应从熔池系统形成的物理过程出发，在稳定性、组织演变规律和性能优化等方面进行更深入、系统的研究。我们致力于开展电弧增材成型技术及理论研究，以推动该技术在现代制造业中的应用。
