八十年代,以焊代铸,以焊代锻的技术,已开始用于大型压力容器筒节、接管和弯头的制造,同时也用于像封头加筒体整体部件的制造;例如:西德蒂禁(Thyssen)公司和GHH公司分别开发的成形焊法(shape Welding),已经取得实际应用,笔者对此曾作过介绍。蒂禁公司采用埋弧成形焊法,曾制造过一个重72吨的压力容器筒节,所需时间仅9 In the 1980s, the technology of welding and casting by forging has started to be used for the manufacture of large pressure vessel tube joints, takeovers and elbows as well as for the manufacture of monolithic parts like head and barrel; for example: The shape welding, developed by Thyssen and GHH, respectively, has been put into practical use and I have introduced this. Adopting submerged arc welding method, the company has produced a pressure vessel barrel section weighing 72 tons, which takes only 9
