摘要
Abstract
Charpy impact test is the most common test method to evaluate metallic materials toughness,and is the important destructive test during welding procedure qualification.The normal welding procedure qualification codes of offshore oil engineering include AWS D1.1,ASME B31.3,API 1104,CCS "material and welding code",etc.The charpy impact test is compared and analyzed from the aspects of scope of standards application,requirements of taking test pieces,test pieces,reduction value of test temperature,acceptance criteria and retest.The similarities and differences of above codes are summarized,and the key technology-test temperature reduction value are discussed according to these codes.关键词
