| 摘 要： | 为了进行焊接热场的三维分析,设计了一个考虑材料物理常数的温度依赖性和更合理的熔池模型的计算程序。为了考核这一程序,以真实管线环焊缝为例,进行了计算.证实了计算程序的准确性、实用性。

| Abstract: | For three-dimensional analysis of welding flow,a computation program has been designed,in which the temperature-dependence of heat physical constants of material and a more reasonable weld pool model are considered.Finally,to check the program,a computation example with a circumferential weld of an actual pipeline was taken It is comfirmed that this program is accurate |
