通过对大型储罐底板焊接变形产生的机理和变形原因的分析,结合生产实践,制订了10000m3大型氮储罐控制底板焊接变形的工艺措施,施工过程中取得较好效果。提出了防止焊接变形的技术措施。
Based on the analysis of the causes and deformation causes of the welding deformation of the large tank floor and the production practice, the technological measures of controlling the welding deformation of the large floor of 10000m3 nitrogen storage tank have been worked out and good results have been achieved during the construction. Proposed to prevent welding deformation of the technical measures.
