摘　　要：金属增材制造以高效、无模具、自由制造等优点,在汽车、舰船、航空航天与电力核能等领域得到了广泛应用,从而推动我国制造行业的新一轮革命。在增材制造巨大应用潜力下,熔焊技术已与金属增材制造工艺产生了深度融合。然而,受限于熔焊与金属增材制造中高温、强弧光的制造环境,不同于传统减材制造的缺陷特点,对制造/成形过程的控形控性提出了严峻挑战。文中综述了熔焊与金属增材制造过程中的缺陷类型以及红外检测技术在过程检测和质量控制方面的应用现状,并对其面临的挑战与发展趋势进行展望。In the backdrop of the huge application potential of additive manufacturing, fusion welding technology had been deeply integrated with the metal additive manufacturing process. Metal additive manufacturing had been widely used in the fields of automobiles, ships, aerospace, electric power and nuclear energy with the advantages of high efficiency, mold-free and free manufacturing, thus promoting a new round of reform in our country′s manufacturing industry. However, the manufacturing environment limited by high temperature and high pressure in fusion welding and metal additive manufacturing, which was different from the defect characteristics of traditional subtractive manufacturing, poses severe challenges for the shape control of the manufacturing/forming process. The types of defect in the fusion welding and metal additive manufacturing process and the application status of infrared detection technology in process inspection and quality control were reviewed in this paper. And also, the challenges and development trends of infrared detection technology in the application of defect detection and control in the metal additive manufacturing process were prospected.
