与焊条和实心焊丝相比,金属粉芯焊兼具熔敷效率高、低烟尘飞溅和焊缝成分可灵活设计等优势,在高强钢焊接领域是极具发展潜力的焊接材料。但是,该类焊丝在实际应用中仍面临焊接参数匹配复杂、焊缝质量稳定性不足等问题。本文综述了高强钢金属粉芯焊丝的研究进展,重点阐述了金属粉芯焊丝电弧物理特性(熔滴过渡行为、电弧稳定性、飞溅特征)的研究现状,分析了粉芯中合金元素(Mn、Ni、Mo、Cr、W、Ti、Cu 等)对熔敷金属微观组织、力学性能、耐磨性和耐蚀性的影响规律,并归纳了金属粉芯焊丝在管道焊接、结构钢焊接及增材制造等典型工程场景中的应用效果。最后,指出了当前研究中存在的不足,并对未来发展方向进行了展望。
Compared with covered electrodes and solid wires
metal-cored wires (MCWs) combine high deposition efficiency
low fume and spatter generation
and flexible weld metal composition design
making them particularly attractive for welding of high-strength steels. Nevertheless
their practical application is still constrained by difficulties in welding parameter optimization and insufficient consistency of weld quality. This paper reviews recent research progress on MCWs for high-strength steels. The arc physical characteristics
including droplet transfer behavior
arc stability
and spatter characteristics
are systematically summarized. The effects of core alloying elements (Mn
Ni
Mo
Cr
W
Ti
Cu
etc.) on the microstructure
mechanical properties
wear resistance
and corrosion resistance of deposited metals are analyzed. Typical engineering applications in pipeline welding
structural steel welding
and additive manufacturing are also reviewed. Finally
existing research gaps are identified and future development directions are discussed.
