摘　　要：叙述了焊接一种大面积铜触头由气体火焰钎焊改为高频钎焊的研究过程。通过更换钎料,设计合适的感应线圈,选用合适的焊接工艺参数,焊接出合格的产品。经肉眼观察、滚压实验、金相分析和扫描电镜的全面检测,触头的高频钎焊质量优良,符合设计要求。该研究对提高铜触头的焊接合格率,降低生产成本,节省焊接时间并大幅提高生产率,减轻劳动强度和改善劳动环境都有极大的价值。This paper describes a large area of copper contact welding by the gas flame brazing replaced by high-frequency brazing process.By replacing the induction coil of solder,design appropriate, the appropriate choice of welding parameters, welding of qualified products. By the virual inspection,rolling experiments,metallographic analysis and scanning electron microscope,a comprehensive inspection,the contact by high-frequency brazing has good quality and meets the design requirements. This study has great value for the company to improve the pass rate of welding of copper contacts,reduces production costs, saves the welding time and dramatically increases productivity, reduces labor intensity and improves the working environment.
