Electromagnetic Acoustic Transducer Nondestructive Evaluation Ultrasonic Imaging Ultrasonic Testing
The Electro-Magnetic Acoustic Transducer (EMAT) consisting of magnets and coil can transmit and receive ultrasonic waves without contact to the specimen. So, it is expected to be used for remote testin g/monitoring of structures in severe condition. This paper discusses techniques of ultrasonic flaw detecting suitable for EMAT, e.g., waveform processing of the received signal and ultrasonic imaging t echnique. We next evaluate the characteristics of a self-produced Lorenz type EMAT such as the amplitude di...
