摘要
介绍了棒材电磁超声探伤仪的设备结构、功能和工作原理,并对棒材内部缺陷进行了识别分析。相比常规水浸式压电超声,电磁超声探伤仪具有调整简便、适应温度范围广等优点,在棒材自动无损检测领域逐渐占据了重要地位。
The equipment structure、function and basic principles of electromagnetic ultrasonic detector for round steel inspection were introduced, and the defect in the steel was recognized. It was compared with PZT ultrasonic testing, Some advantages of EMAT were introduced, such as easy adjustment, adapt to wide temperature range and so on, so an important position gradually in the field of NDT was occupied.
