摘　　要：激光束与其它热源复合,通过两种热源的协同效应,弥补单纯激光焊接的不足之处,可以焊接两种单独热源难以完成的接头形式,获得单热源难以达到的高效焊接效果。文中对已经在工程上得到应用的激光与TIG电弧、MIG电弧、双电弧、等离子弧、高频感应热以及搅拌摩擦热的复合热源焊接技术进行了比较,归纳了它们的原理、特点及应用范围。此外,总结了上述几种复合热源焊接技术的国内外最新研究进展,介绍了激光-电阻缝焊等几种最新的基于激光复合热源焊接方法,评价了其特点和应用前景。最后指出激光复合热源焊接技术是今后激光焊接的发展趋势。Attributing to synergistic effect, the combination between laser beam and other heat sources can remedy the defect of pure laser beam welding, and weld especial type of joint, and obtain high effective welding which could never be achieved by utilizing solo heat source. Several hybrid welding techniques by using compounded heat sources based on laser are compared, for example the combination between laser beam and TIG arc, MIG arc, double arc, plasma arc, high frequency induction heat as well as friction stir heat respectively. Furthermore, their principles, characteristics and application area are introduced. The latest development of research on the hybrid welding techniques mentioned above both at home and abroad is summarized; properties and application potential of several new hybrid welding techniques, such as hybrid laser and resistance seam welding, are evaluated, which laser beam welding in combination with other heat sources is a development trend of laser welding in the future.
