摘　　要：钽在武器装备、原子能、航天领域具有重要作用,但钽的焊接极为困难,仅有少数国家具备焊接能力。综述了国内外钽焊接的主要研究机构、研究内容、研究现状和发展趋势,调研结果表明:钽的焊接热源出现由弧焊向激光焊、电子束焊转变的趋势;主要研究趋势为基于焊接有限元模拟、材料计算结果来改进焊接工艺,进而获得高质量焊缝。国内钽焊接方法较为齐全,但研究深度不足,尤其是焊缝成形机理研究、焊缝组织调控方法、有限元分析等方面几乎处于空白阶段,需要大量深入的理论研究突破技术壁垒。Tantalum plays an important role in the fields of weaponry,atomic energy,and aerospace,but the welding of tantalum is extremely difficult.Only a few countries at home and abroad have welding capabilities.This article reviews the main research institutions,research content,research status and development trends of tantalum welding allover the world.The survey results show that:the heat source of welding tantalum changed from arc welding to laser welding and electron-beam welding.The main research trend is to improve the welding process based on welding finite element simulation and material calculation results to obtain high-quality welds.Although welding techniques in China are relatively complete,the research depth is insufficient.In particular,there is almost no research on the formation mechanism,structure control method of weld-ing joint,and finite element analysis. In-depth theoretical research is required to overcome the technical barriers.
