Abstract
In this article,it summarized repairing ultra-high pressure vessel defects from two aspects of metallurgy and process,emphasized the selection of welding parameter,welding method,welding material,heat treatment and other processes commonly used in monocoque ultra-high pressure vessel overlaying welding repair.Finally,it pointed that it should improve mechanical performance of welded joint from welding material,heat treatment,welding method and other aspects in repairing ultra-high pressure vessel defects,pay attention to the matching of welding material and base metal performance,and it also should adopt corresponding measures to reduce the diffusible hydrogen content.After repair the strict nondestructive testing should be conducted and make the necessary hydraulic pressure test.关键词
