乙烯管线施工中下向焊技术的应用

Application of Down Hill Welding Technique in Construction of Ethylene Pipeline

介绍了长距离输送管线全位置立下向焊技术的应用实例。阐述了在控制焊接工艺、降低焊接成本、提高生产效率、提高焊接质量等方面的经验,也为手工立下向焊技术的应用提供了可供参考的工艺参数。

The application of full position down hill welding of long distance pipeline was introduced. The experience in controlling welding process, reducing welding cost, improving production efficiency and improving welding quality were expounded. It also provided the reference process parameters for manual down hill welding.
