Dry and contactless inspections by means of EMAT ultrasounds

Dry and contactless inspections by means of EMAT ultrasounds

EMAT transducers were developed for use in dry and contactless inspections as an alternative to the use of piezoelectric transducers. While the sound in the piezoelectric transducer is generated in the transducer and transmitted to the workpiece through a coupling, an EMAT induces ultrasonic waves within the material to be inspected by means of two magnetic fields that interact with each other. This study analyses the ultrasonic beam generated by conventional EMAT transducers and Phased-Array EMAT transducers. With regard to conventional transducers, the influence of the coil geometry has been analysed. As regards the Phased-Array EMAT transducers, their configuration and improvements that they offer with respect to conventional transducers have been analysed.
