摘要
本文主要介绍了TP304、TP347这两种进口奥氏体耐热不锈钢制承压管道在实际施工焊接过程中经常容易出现的缺陷以及它们形成的主要原因,并根据焊接工艺评定结果和实际施工中的效果而提出解决它们的一些办法。
The defects and their reasons found in site welding of pressure pipeline made of imported heat- resisting stainless steels TP304 and TP347 are introduced in the paper. On the basis of welding procedure qualification and effect in practical welding, the method to solve those defects is further put forward.
