Abstract：

The large pressure vessel has always been a research hotspot due to its wide use, multitudinous forming technology and high manufacturing difficulty. The research status in China, including manufacturing processes and their characteristics on heavy pressure vessel thick-wall sealing head were systematically introduced from the aspects of the overall forming technologies including hot stamping, spinning technology, explosive forming and rotating die forging method, etc. and split forming technology(welding forming). In addition, the key technologies of forming processes in quality control were outlined briefly. Meanwhile, the causes of forming defects such as wrinkling, cracking produced by several typical forming process were analyzed,and some of the major control measures were deduced. Finally, the research status of each forming process and processing characteristics was summarized.
