In this paper,the main shell of the 12Cr2Mo1R steel reforming reactor is welded with welding materials from Harbin Welding Research Institute. All performance can meet the national standards and equipment design requirements of the reforming reactor,which shows that the quality and stability of domestic welding materials reach the level of similar foreign products,and promotes the localization of heat-resistant steel welding materials,while using domestic welding materials can greatly reduce manufacturing costs. 重整反应器 12Cr2Mo1R 国产焊材 焊接工艺 reforming reactor 12Cr2Mo1R domestic welding materials welding procedure TG42 2022-03-08 10 50
