摘要
自动焊接技术已广泛应用于大口径、高钢级长输油气管道工程建设,但目前缺乏成熟的自动焊施工技术体系。根据自动焊施工特点,结合长输管道自动焊施工实践经验,以发挥自动焊施工工效、保证施工质量为中心,从设计、管材、焊接、无损检测、施工组织等方面提出了自动焊施工的技术准备要点,剖析了焊接人员、技术储备及信息化焊接质量管理现状,并提出了合理化的应对措施,以期为今后管道工程推广自动焊施工方法、提高焊接效率、发挥技术优势提供参考。
Automatic welding technology is widely used in the large-diameter and high-grade steel pipeline projects,but no mature automatic welding technology system is available at present.According to the construction characteristics of automatic welding,with reference to practical experience in automatic welding of long-distance pipelines,key points of technical preparation for automatic welding were put forward in terms of design,pipe,welding,nondestructive testing and construction organization,focusing on improving construction efficiency and ensuring the construction quality.In addition,the current situation of personnel,technical reserve and informatized welding quality management was analyzed,and the reasonable measures were proposed to provide references for the follow-up promotion of automatic welding technology in pipeline projects,improve the welding efficiency and take full advantages of the technology.
