| 摘 要： | 洪江电站超大型弧形闸门焊缝较多，焊接变形较大、焊接变形控制困难。闸门制作中，利用多种焊接变形控制技术，对闸门制造全过程焊接进行了跟踪和研究。通过采用预留收缩余量和反变形量，钢性加固，合理选择焊接方法，调整焊接顺序等措施保障了产品焊接最终质量。该闸门制造焊接质量控制经验可供借鉴。

| Abstract: | The super radial gate for the Hongjiang Hydropower Station has many welding joints so that it is big in welding deformation and difficult to control the welding deformation. In the manufacturing of gate, we use many welding deformation control techniques and adjust the welding sequences to guarantee the final welding quality of gate. The experience of welding quality control in the manufacturing of such gate can be used for reference. |
