摘要
双层卷焊管即邦迪管，是将双层带钢经加热钎焊熔为一体，经成型为双层卷焊管，过去国内外都使用炉内加热焊接，生产受到限制。本文介绍在生产线上的连续焊接方法，是采用通电加热法并有相应保护方法。讲述了连续焊接工艺、加热时间计算、输入功率计算及电源选择，焊接设备原理及容量设计，总结了采用导电加热焊接法的优点。可供各生产厂家和设计、制造部门参考。
continuous welding technique for double-layer welded pipe is introduced. In this paper,technology parameters,the calculation of heat-time and input energy, the selection of power source and the principle of welding equipment and its capability design are discussed. Also,the advantages of electric-heat welding is summarized.
