AbolishedMethod of electromagnetic acoustic inspection for metal materials - Part 2: Standard practice for ultrasonic testing using electromagnetic acoustic transducer(EMAT)techniques
金属材料电磁超声检验方法 第2部分：利用电磁超声换能器技术进行超声检测的方法
Application Summary AI generated
This standard specifies the methodology for ultrasonic testing of metal materials using electromagnetic acoustic transducers (EMATs), which generate and receive ultrasonic waves without direct contact or couplant. It is applied in the metallurgy industry for inspecting metal products such as plates, pipes, and bars during manufacturing or in-service evaluation, particularly in high-temperature or rough-surface conditions where conventional contact ultrasonic testing is impractical.
