窄间距钨极脉冲氩弧焊在双套管废热锅炉制造中的应用

Applying Narrow-gap TAW-P for Production of Double Tube Waste Heat Boiler

在双套管废热锅炉的制造中,采用窄间距钨极脉冲氩弧焊新技术。并对喷嘴、规范参数、坡口形式等作了相应改进,使双套管、联箱、集气管的焊接全部实现了钨极氩弧焊打底,从而提高了双套管废热锅炉的质量。

In the production of double tube waste heat boiler, the new technologies of narrow-gap TAW-P are used, and the nozzles, normal parameters and groove shaps are improved.They cause all the welding of double tubes, joint boxes and gas-collecting tubes to realize the backing weld of TAW-P.The quality of the double tube waste heat boilers have been improved.
