摘　　要：针对换热器管板堆焊实际情况,确定了堆焊试验模型及工艺参数,并进行了堆焊试验。同时,在相同模型及工艺条件下,利用Ansys软件进行了堆焊数值模拟,使用APDL语言进行参数化编程,得到了模拟结果温度场和应力场的分布规律。通过试验结果与数值模拟结果的对比分析,证明了分析方法的合理性,对于今后产品局部结构优化设计、焊接残余应力分析及焊接工艺优化等均有直接帮助。In view of the actual situation of heat exchanger tube sheet welding, determines the welding test model and its process parameters, and a welding test was carried out. Meanwhile, under the condition of the same model and process,welding numerical simulation are carried out using Ansys software, parameterized using APDL language programming, and obtained the distribution of temperature field and stress field. Through comparing and analyzing the test results and the numerical simulation results ,the analysis method was proved to be reasonable. This approach have a direct help for the optimal design of the local structure of products, the analysis of the welding residual stress, the optimization of the welding process and so on.
