某核电站RP龙门架箱形钢结构梁制作工艺

Manufacture Process of Steel Box Girder for RP Gantry in Some Nuclear Power Station

钢结构工程中,箱形钢梁制作工艺复杂,焊接变形控制困难。通过从下料、组装、焊接、矫正等方面详细介绍了核电站RP龙门架箱形钢结构梁的制作工艺过程,该过程保证了箱形钢梁的整体几何尺寸,同时又保证了焊接质量并有效控制了焊接变形,取得了一定经济效益。

In steel structure project,fabrication process of steel box girder is complex,so it is difficult to control welding deformation. This paper introduced the fabrication process of steel box girder for RP gantry in nuclear power station from the material,assembly,welding and correction. The fabrication process ensures the overall geometry of box girder,and guarantees the effective control of welding deformation and welding quality,achieves a certain economic benefits.
