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.
