摘　　要：简述了无电焊接技术的原理,从无电焊笔的燃烧过程、熔渣与焊缝金属的分离及保护、焊缝金属与焊接母材的界面强化这3大关键性问题展开叙述,结合目前无电焊接工艺的优化及应用,综述了无电焊接技术当前的研究进展,分析了无电焊接技术面临的问题并展望其前景。在无电焊接技术的核心问题,即焊笔燃烧过程研究中,已形成了以铝/氧化物放热体系为热源的焊笔配方。在此基础上,作者课题组成功引入了铝/硫酸盐放热体系加大无电焊接热输入,对进一步拓展无电焊接技术的应用领域提供了理论基础及技术支撑。Principle of non-electric welding technology was described briefly.It was introduced from three key problems of burning process of non-electric welding pen,separation and protection of slag,and weld alloy and interface strengthening between weld metal and welding base metal.Combined with optimization and application of non-electric welding technology at present,current research progress of non-electric welding technology was summarized,and problems faced by non-electric welding technology were analyzed and its prospect was prospected.In the research of the core problem of non-electric welding technology,that was burning process of non-electric welding pen,formula of welding pen with Al/oxide exothermic system as heat source has been formed.On this basis,the author’s group has successfully introduced Al/sulfate exothermic system to increase heat input of non-electric welding,which provided theoretical basis and technical support for further expanding application field of non-electric welding technology.
