摘　　要：利用ANSYS软件对用钽制换热管、Ta/16MnR制管板的管板式换热器中氩弧焊接接头进行了数值模拟,得到了4种尺寸组合焊接接头的温度场数值模拟结果。通过对模拟结果分析,表明钽-钢复合板的钽层厚度是影响焊接质量的主要因素。为了使钽-钢复合板钢层在焊接过程中不出现熔化,钽层厚度要达到2.5mm。这一模拟结果通过文献中的实验结果得到了验证。By using ANSYS, the temperature field of tube to tube sheet argon-arc welded joint which consisting of tantalum （Ta） tube and Ta/ 16MnR clad sheet was simulated. The numerical simulation results of four kinds of welded joints were obtained. The results show that the thickness of tantalum layer of Ta/16MnR clad sheet is primary factor for welding quality. The tantalum layer thickness of Ta/16MnR clad sheet needs 2.5mm, otherwise the 16MnR steel beneath tantalum layer would melt. The numerical simulation result has been substantiated by the experimental results in reference.
