| Abstract: | A lot of industrial equipment are in operation under high temperature condition. So the metal materials are easy to cause creeping. In order to prevent welded structure from creep cracking and failure this article introduces failures of welded structure under high temperature and discusses the beginning and developing of creep cracking, status and features of creep cracking and failure and cause of creep cracking and impact factors. It finally provides precaution based on the discussion. |
