摘要：

This paper describes some results on the ultrasonic analysis of adhesively bonded aluminium plates using normal incidence radially polarised shear wave ElectroMagnetic Acoustic Transducers (EMATs). The EMAT system presented here has undergone significant development work and improvements compared to previously published examples. ((9,19)) The electronic 'deadtime' of the system has been reduced to approximately 1 microsecond and the frequency range over which measurements can be taken has been extended. The capability of the technique to detect gross and subtle defects is demonstrated.
