摘要: 电弧熔丝增材制造具有设备成本低、制造效率高等特点,在航空航天、舰船、武器装备等领域具备广阔的应用前景。在复杂热循环的条件下,电弧行为、熔滴过渡、熔池流动与凝固以及沉积内部热积累效应等因素的耦合作用是决定结构成形与质量的关键,也是实现控形控性的理论基础。基于电弧熔丝增材制造的物理过程数值模拟研究现状,综述了不同热源类型电弧增材制造工艺过程中的物理机制,揭示了不同沉积过程传热传质行为的内在关联与区别。在此基础上,概述了常见形貌缺陷的形成机理、影响因素与其抑制策略,总结了不同主动控热控形控性方法的机制与特点,探讨了当前电弧熔丝增材制造传热传质数值模拟过程中存在的主要问题,并对其未来发展应用提出了思考与建议。

Abstract: Wire Arc Additive Manufacturing (WAAM), which is able to create large metal components with high deposition rate and low equipment cost, has increasingly attracted attention from industrial sectors, including aerospace, shipbuilding, military equipment etc. During WAAM, the combined effects from arc characteristics, droplet transfer behaviour, molten pool flow and solidification, and heat accumulation under the complex thermal cycle plays a critical role in the deposition formation and quality, which also the theoretical basis of realizing the geometry and material properties in control. The emerging research on the numerical simulation of WAAM is reviewed in this article, and a comprehensive overview of the physical mechanism of WAAM based on different heat sources is also provided. The heat and mass transfer produced in different WAAM process are described to reveal their intrinsic connections. Common defects are depicted, including formation mechanism, inside factors, inhibition strategy. Methods for controlling the deposition process, geometry and quality are discussed, take into account the physical characteristics of WAAM. It is concluded in this paper that many challenges still exist in the numerical simulation of the WAAM process, and critical thinking and suggestions are proposed for its future development and application.

Key words: wire arc additive manufacturing, numerical model, heat and mass transfer, defect, quality control
