摘　　要：本文系统总结了钼及钼合金焊接技术的研究现状和最新进展,分别介绍了近年来电子束焊、钨极氩弧焊、激光焊、电阻焊、钎焊和摩擦焊等6种焊接技术应用于钼及钼合金焊接所取得的进展和发现的问题,论述了各种焊接技术的特点,结合钼合金焊接性特点对各种焊接技术应用于钼及钼合金焊接的发展前景进行了分析和展望。Current research status and recent advances in joining technology of molybdenum and molybdenum alloys were systematically summarized. The recent progress and problems of six welding technniques used in welding mo-lybdenum and molybdenum alloys including electron beam welding, TIG welding, laser welding, resistance weld-ing, brazing and friction welding, were introduced respectively. The characteristics of various joining techniques were discussed. Based on the weldingability of molybdenum alloys, analysis was made on the development prospect of a variety of joining techniques applied to molybdenum and molybdenum alloys welding.
