This paper introduces a new process of pipe root welding called surface tension transition(STT). Comparing with other process, this new process can not only gain excellent root weldingquality but also have quite fast welding velocity. It does not require welder with higher operatingtechnique. STT is a new transition method similar to short circuit transition or short arc transition. The important feature of this process is that welding current is not related with velocity ofwelding wire feeding. Therefore heating can be controlled well to get proper melting depth and toeliminate cool lap which occurs often in ordinary process. Meanwhile it can reduce 90% of weldingsplash and 50% -70% of smoking dust.

本文介绍一种用于管道根焊的新工艺。与其他工艺相比,表面张力过渡工艺(STT)不仅可以获得极好的根焊质量,而且具有相当的焊接速度,对焊工也无更高的操作技巧要求。STT是一种类似于短路过渡或短弧过渡的新过渡方式,其重要的特点是焊接电流与送丝速度无关,因此可以更好地控制热量输入而得到合适的熔深,并消除普通工艺可能产生的冷搭接现象,同时使焊接飞溅减少了90%、烟尘减少了50%~70%。
