STT根焊技术在东西伯利亚—太平洋管道工程中的成功应用

STT Root Welding Process was Successfully Applied in East Siberia-Pacific Ocean Pipeline Project

简要介绍了STT技术工作原理,详细叙述了STT技术应用于半自动根焊时需调整设定的参数及其在焊接过程中的作用。通过东西伯利亚—太平洋管道应用STT根焊技术的成功先例,对管道焊接推广STT技术具有一定的借鉴作用。

It briefly introduced working principle of STT process, and detailedly narrated parameters and its effects which need adjust and set up in STT semi-auto root welding process. At last it introduced SIT root welding technology application situation in East Siberia-Pacific ocean pipeline. This will provide reference to pipeline welding.
