摘　　要： 导管安装感应钎焊技术是为了实现导管的现场安装而提出的一种特殊的工艺技术。由于焊接时不同工艺参数的差异,导管焊接区域温度场分布差异较大。介绍了导管安装感应钎焊实现方法、热输入输出模型,建立了温度场分布数值模拟模型,并用有限元软件进行数值模拟,分析了钎焊温度分布规律,为该类型焊接工艺的制定提供了依据。 On-site induction brazing of tube technology is a special welding process aimed to fulfill tubes＇ field installation. Due to the difference of various welding process parameters, there is a large difference of temperature distribution during on-site inductions in welding area. The implementation method and the thermal transfer model were introduced. The model of temperature distribution was established and simulation analysis was made by finite element software. The distribution of brazing temperature was given and the simulation results can provide references for the similar brazing.
