doi:10.3901/JME.2025.06.092

Abstract

Abstract: As a low-energy, sustainable green manufacturing technology, wire arc additive manufacturing (WAAM) technology is very suitable for low-cost and high-efficiency manufacturing of large and complex components. However, the manufacturing requirements of complex structures and high-performance components pose great challenges to the WAAM equipment system. At present, the forming accuracy, quality and stability of the WAAM equipment system limit its further development and application. The technical principles of WAAM are expounded. The development status of WAAM equipment system is summarized from the aspects of mechanism freedom, forming precision and quality, forming efficiency and heat input control. Combined with the application examples of WAAM technology in the industrial manufacturing, its broad application prospects are discussed. Finally, the future development direction of this field is prospected. By summarizing the equipment systems and applications, the aim is to promote further industrial applications of WAAM.

Key words: wire arc additive manufacturing, mechanism freedom, forming quality, forming efficiency, heat input
