| 摘 要： | 针对管线钢堆焊,考虑了材料热物理性能参数与温度的非线性关系,建立了焊接过程的数学模型和物理模型。利用ANSYS软件的APDL语言编写程序,实现了在移动热源载荷下的焊接有限元计算,分析对比了不同焊接工艺参数对焊接温度场的影响程度,并拟合出了焊接板厚与T8/5的经验公式。

| Abstract: | The mathematical model and physical model for pipeline welding thermal process are set up concerning the thermo-physical performance parameters and the nonlinear relation between the phase change latent heat and the temperature.Based on ANSYS APDL developing platform,a program is designed to solve the calculation of welding finite enement under movable heat loads.The influence of different welding processing parameters are analyzed and matched on welding temperature field. |
