摘要
电弧熔丝增材制造(Wire and arc additive manufacturing,WAAM)作为金属增材制造技术的一个重要分支,以电弧为载能束逐层熔化金属丝材,适合中大尺寸复杂金属构件的快速制造,在航空航天、国防领域展现出广阔的应用前景。然而,成形精度低、过程稳定性差、缺陷控制难等问题限制了该技术的高效、高质量发展与应用。为满足高可靠、高自动化与高质量制造的要求,对WAAM全过程实施在线监测与闭环控制已势在必行。分析了WAAM成形质量的特征参量及其主要影响因素,阐述了WAAM过程传感方法的原理与研究现状,总结了WAAM成形质量控制方法,指出了未来WAAM过程传感与控制技术的主要发展方向。
As an essential branch of metal additive manufacturing,wire and arc additive manufacturing(WAAM),using an arc as the energy beam,is suitable for rapidly fabricating medium-to-large scale metal components and exhibits a wide application prospect in aerospace and national defense.Nevertheless,the issues of low forming accuracy,poor process stability and difficult defect control restrict high-efficiency and high-quality development and application of this technology.It has been urgently to implement online monitoring and closed-loop control during the entire WAAM process for the demand of reliable,automatic,and quality-ensured manufacture.The characteristic parameters and their main influential factors are analyzed.Principles and research status of process sensing methods are illustrated.Control methods of forming quality in WAAM are summarized.Eventually,principal developing orientations of process sensing and control in WAAM are proposed.
