- 摘要:
- 焊接天然气空冷器的传统工艺是SMAW方法，生产效率低，经济效益差,焊缝质量难以控制。文章介绍了将药芯焊丝CO2气体保护焊工艺应用于空冷器套管焊接的方法、焊接设备、焊接工艺参数、操作要点及注意事项。采用该方法焊接，不仅焊缝美观，各项技术指标符合设计要求，而且提高生产效率1.52倍，焊接综合成本下降8%，值得在油田同类产品的焊接工程中推广应用。
The traditional welding method used for natural gas cooler manufacture is SMAW which has the shortcomings of low production efficiency, low economic benefit and difficult welding quality control.This paper illustrates the welding method of applying flux cored CO2 welding technique in air cooler casing welding as well as its welding equipment, welding process parameters, operation key points and matters for attention.The welds made by this welding method have good appearance and their technical indexes meet the design requirements, furthermore the production efficiency increases 1.52 times and synthetic cost decreases by 8%.This welding method is worthy to be extended to similar welding projects in oilfields.2010,5(5): 59-61 收稿日期：2009-1-3分类号：TE973.4作者简介：代渊雄（1960-），男，湖南武冈人，高级焊接技师，获IWS资质，现从事锅炉压力容器和石油天然气管道焊接工作。参考文献：
