海洋平台及导管架焊接预热施工方法

Construction method for welding preheating of offshore platform and jacket

海洋平台及导管架在焊接作业前通常都需要对母材进行预热作业,由于海洋平台及导管架节点类型较多,形式较为复杂,在焊接预热时只有采用合适的施工方法才能保证预热效果,避免产生焊接质量问题。本文针对海洋工程中不同的节点形式给出合理的施工操作方法以指导施工。

Offshore platforms and jackets usually need to preheat the base material before welding operations.Because offshore platforms and jackets have many types of nodes and their forms are more complicated,only suitable construction method can be used for welding preheating in order to ensure the preheating effect and avoids welding quality problems.The reasonable construction operation methods for different node forms in ocean engineering has been put forward in the text to guide construction.
