摘　　要：为了研究镀锌钢板卷对接头激光钎焊传热过程,本文通过有限元方法对激光钎焊温度场的演化进行了数值模拟和分析。为了验证计算模拟的准确性,采集并绘制了焊缝附近不同位置的热循环曲线,得到的实验结果与模拟曲线一致,验证了温度场模拟的准确性。In order to study the heat phenomenon of laser brazing of the flange butt joint,the numerical simulation of temperature field was carried on by the finite element method,based on the forming characteristics of the flange butt joint and the principle of laser brazing.Temperature field thermal cycle curve measurement system was built.The thermal cycling curves of different positions near the weld were measured,based on Labview software through the data acquisition card and thermocouple.The experimental results were in agreement with the simulation results.The accuracy of the simulation result of the temperature field was verified.
