Abstract

As an important branch of the nondestructive testing field, ultrasonic testing is widely used in the steel, electric power, petroleum, transportation, and medical and other industries. In the process of ultrasonic testing, the ultrasonic transducer is the core component of excitation and reception of ultrasonic waves, mainly including the piezoelectric ultrasonic transducer and the electromagnetic acoustic transducer (EMAT). Compared with the piezoelectric ultrasonic transducer, EMAT has many advantages, such as being non-contact, without the need for the coupling medium, and easy to produce the shear horizontal (SH) wave. In particular, it can be applied under a high-temperature environment, or there is an isolation layer, and other special situations [1]. It is of great value and a wide range of applications.
