Application of Several Auxiliary Tools in the Construction of Pipeline Automatic Welding

摘要: 介绍了钢管局部变形检测尺、内防风清扫器以及轨道装夹校正器3种辅助工具在自动焊施工中的应用和效果。通过中俄东线天然气管道工程试验段一期的现场验证，利用钢管局部变形检测尺，可由单人快速完成管口变形量检测，避免因变形造成管道组对等环节的停窝工；利用内防风清扫器，可有效保障内根焊稳定，降低焊接缺陷；利用轨道装夹校正器，单次导向轨道安装时间可节约2~4 min。3种辅助工具结构合理、使用简便，能够促进自动焊施工的有效进行。

Abstract: This paper introduced the application and its effect of the three kinds of auxiliary tools, such as local deformation detection rule, internal wind deflector and rail clamp corrector for pipeline automatic welding in construction. Through the on-site verification of the pilot section of Chi-na-Russia eastern oil and gas pipelines, the local deformation of steel pipeline could be quickly detected by a single person with deformation detection rule for effectively reducing the idling work in pipe pair welding for pipeline deformation, and the roots welding stability and quality can be effectively controlled by using internal wind deflector for reducing the defects in welding. The installation time of the single guide rail can be saved for 2 - 4 minutes by using the rail clamp corrector. These tools have the advantages of simple and reasonable structural design, and convenient operation, which can promote the pipe automatic welding effectively.
