针对组焊工艺特点、施工工艺、施工检测四个方面进行了叙述和分析,本文提出了几点看法,认为在当前工艺装置已日趋大型化单机化,压力容器已向大型化、高性能发展,对制造容器的钢材亦提出了高要求,阐述了cf-62高强、耐低温钢用于大型压力容器尤其在焊缝密集、制造加工较繁杂的球形容器现场施工的可行性
According to the characteristics of welding technology, construction technology and construction inspection, the paper makes some comments and analyzes. This article puts forward some suggestions that the current process equipment has been increasingly large-scale single machine, the pressure vessel has been large-scale, high performance development, High demand is also put on the steel used for making containers. The feasibility of on-site construction of CF-62 high strength and low temperature resistant steel for large-scale pressure vessels, especially for weld-intensive and complicated manufacturing and processing is expounded
