摘　　要：针对Fe3Al基合金工程化应用亟待解决的焊接问题,从熔焊、固相焊及钎焊3个方面综述了目前国内外Fe3Al基合金焊接技术的研究现状和最新进展。对不同焊接工艺下焊接接头的显微组织与力学性能做了详细介绍。并探讨了目前焊接技术中存在的问题及解决措施。最后展望了Fe3Al基合金焊接技术的发展趋势。For the welding problem which requires immediate solution before engineering, the recent research and development in welding technology of Fe3 Al based alloys are summarized through 3 aspects including fusion welding, solid phase welding and infrared brazing. The microstructure and mechanical properties of the weld joint after different welding procedures are illustrated. Problems during welding procedure and the corresponding resolving measures are also discussed. At last, the future trends of welding technology are prospected.
