焊接是压力容器制造的关键技术之一。埋孤焊的焊前准备相当重要,焊接规范也很严格,我们在几年的生产中总结出一套自己的经验;钨极氩孤焊焊丝的改进,也是通过生产实践检验,效果很好。本文重点论述了这两种焊接方法的使用效果以及工艺改进情况。
Welding is one of the key technologies of pressure vessel manufacturing. It is very important that the preparation of welding before welding is very important and the welding specifications are very strict. We have summed up a set of our own experience in the production for several years. The improvement of the welding wire of tungsten argon welding is also verified by the production practice and works very well. This article focuses on the use of these two welding methods and process improvements.
