随着经济发展,石油开采也由陆地逐渐转为海上,海洋石油的战略地位已经逐步提高,因此每年都需要建造大量的海上平台,近些年深海平台的需求日益变多,相对浅海而言,深海对于平台的质量要求更高。平台建造中钢结构的连结,基本上都要依靠焊接技术,因此焊接技术的重要性不言而喻,但在施工过程中,由于焊接产生的焊接残余应力和残余变形,严重影响着工程的质量、安装进度和使用,因而需要采用适当的方法去控制。
With the economic development, the oil exploitation has gradually shifted from land to sea. The strategic position of offshore oil has gradually increased. Therefore, a large number of offshore platforms need to be built each year. In recent years, the demand for deep-sea platforms has been increasing. In the relatively shallow sea, Deep sea quality requirements for the platform higher. The connection of steel structure in the platform construction basically depends on the welding technology, so the importance of welding technology is self-evident, but in the process of construction, the welding residual stress and residual deformation caused by welding seriously affect the quality of the project , Installation progress and use, and therefore need to use the appropriate method to control.
