摘　　要：为预测液压支架立柱活塞杆堆焊过程的温度场分布情况,以ANSYS软件为平台,运用APDL编程及单元生死技术,在常温20、150、300℃预热情况下对活塞杆模型进行了焊接瞬态热分析,得到了立柱活塞杆的焊接温度场分布规律。结果表明,常温堆焊焊缝容易形成淬硬组织,预热能降低焊缝淬硬组织的形成倾向。In order to predict the distribution of the temperature field during the surfacing process of a hydraulic support column piston rod,the ANSYS software was used as a platform,the APDL programming and the unit life and death technology were applied to perform the transient thermal analysis of piston rod model under 20,150,300℃preheating temperatures.The distribution of the welding temperature field of the column piston rod was obtained.The results show that hardening microstructure is easy to form in surfacing weld at room temperature.Preheating can reduce the formation tendency of hardening microstructure in weld.
