| 摘 要： | 夏比冲击试验是一种常用的评定金属材料韧性的试验方法,是焊接工艺评定过程中一项重要的破坏性试验。海洋石油工程常用的焊接工艺评定标准包括AWS D1.1、ASME B31.3、API1104、CCS《材料与焊接规范》等,主要从标准适用范围、取样要求、试样、试验温度降低值、结果评判、复验六个方面进行分析比较。归纳总结以上标准的异同点,并重点讨论试验温度降低值关键技术。

Comparison and analysis of charpy impact test for welding procedure qualification of offshore oil engineering |
| |
| 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. |
