- 摘要:
- 石油部第七工程公司在承担由日本引进的50000m3四台双盘式浮顶罐的施工中,为了保证施工质量,在罐底焊接中分析引起底板变形的原因后,提出不设置夹具大板焊接减小变形的措施,其具体作法是改变焊接顺序,采取反变形措施及减少板端留头。因此在控制焊接变形方面取得了一定的效果。
In order to ensure construction quality measures for reducing weld deformation of floor plate without clamps have been taken by the Seventh Engineering Cons-traction Co.of petroleum Industry Department on the basis of analysing the defor-matron reasons during constructing four 5.0000m3 dual-deck floating roof tanks intro-duced from Japan.The main measures to be tken a re: changing the welding seyuences, taking deformatian prevention mea nsand minimizing the allowance of plate ends By taking such measures reduction of weld deformation has been achieved1987,4(4): 13-17参考文献：
