油气管道手工焊接工艺

The Mannal Welding Processing for Oil & Gas Pipeline

油气管道安装技术的发展方向是采用自动焊接技术。国外半自动和自动焊接技术已经较为广泛使用 ,而国内以手工焊为主的施工技术与之存在巨大差距 ,显然搞好技术引进、开发是努力方向 ,但发展和完善现有的手工焊工艺仍有积极意义。简单介绍国内近年引进的较为普遍采用的管道手工下向焊接技术 。

The developing direction of the installation technique for oil & gas pipeline is the automatical weiding technology.At abroad,the semi automatical welding technologies are used for and wide,but at home,the manual welding processing for construction has still gveat difference with the semiautomatical welding technology,At present,the direction is the technological import and develoment,but the improving and developing the existing manual welding processing will be possessed of great positive significance.It is intruduced in this paper some in last years imported most in use manual downward welding technologies and some most in use pipeline manual welding processings as well as the problems needing attention by selecting the manual welding processing.
