| Abstract: | Several judgment methods of post-weld heat treatment exemption were introduced and compared,with emphasis on the engineering critical evaluation method and how to apply this method to the evaluation of the necessity of post-weld heat treatment. Finally,taking the post-weld heat treatment of offshore pile of an offshore platform as an example,the effects of allowable defect size,stress and fracture toughness on the safety of the structure are analyzed quantitatively,which provides a new basis for the exemption of post-weld heat treatment for offshore platform thick plate. |
