摘　　要：薄板钛合金结构在焊接生产中得到了广泛的应用。焊接过程的传热问题十分复杂,焊接过程中的温度分布对于焊接变形有着重要的作用。针对平板TA15钛合金对接接头,对焊接温度场进行了仿真模拟计算,得出了焊接热循环曲线,并进行了试验验证。经过测量比对,焊接热循环曲线变化趋势与模拟所得结果大体一致,说明了模拟计算的正确性。The sheet titanium alloys use widely in welding field.The diathermanous problem in welding process is very complicated,which significantly inflect the temperature distributing.The temperature cycle curve was gained by means of simulation.By measuring,the test results were in accord with numerical results,thus the results of simulation analysis were correct.
