摘要:: STT气体保护焊是提高管道根焊质量的有效方法，与手工焊相比具有焊缝质量好，噪声小，无污染，焊接成本低等优点。通过对X60和X52两种管材进行根焊试验，探索其在长榆管道焊接中的应用，为同类焊接提供借鉴。文章介绍该试验的焊接工艺及检验结果，并分析STT气体保护焊的效率及经济效益。
Compared with welding by hand, STT gas shielded welding is an effective method for improving pipeline welding quality. It has advantages of better quality of welding seam, lower noise, no pollution and lower cost and so on. The application of STT gas protective welding in long-distance pipeline was developed via the two X60 and X52 pipeline materials welding. And the welding technology, check up results and operation proposals on the trial were also introduced.
