Test verifies and simulation on welding temperature field of 785 high strength steel for hydraulic support

  • 摘要: 为了优化785高强度钢焊接工艺参数,能够提供焊件上典型位置的准确热循环曲线,掌握和预测焊接过程中及焊后焊件组织、性能变化规律,采用ANSYS有限元软件对20 mm板材焊接温度场进行数值模拟,并将模拟结果与相同工艺条件下焊接试验数据进行比较.结果表明,焊接热循环曲线的模拟结果与试验数据高度吻合;模拟焊接热影响区的宽度与实际测量值基本一致;从母材到熔合区,板条贝氏体逐渐减少,粒状贝氏体逐渐增加,晶粒尺寸也逐渐变得粗大.

     

    Abstract: The as-received material was subjected to obtain thermal circling curves of typical position by ANSYS software numerical simulation in the different welding technological parameters on 20 mm thick plate to optimize welding process parameters and predict microstructures and properties for improving welding quality, compared with the simulation results and the experimental results in the same welding process conditions. It was found that the values of the thermal circling curves were close to the values measured; the simulation width of welding heat affected zone was basically the same as the measured values; the lath bainite was gradually reduced, the granular bainite increased and the grain size also became coarse from base metal to fusion zone.
