Abstract

Electromagnetic acoustic transducers (EMATs) can generate and detect ultrasonic waves in a conductive specimen by noncontact electromagnetic coupling. This feature gives EMATs an advantage over conventional ultrasonic transducers : theoretical modeling and formulation based on elastodynamics and electromagnetics can be obtained. In this research, HIP joint inspection by using EMATs was analyzed numerically. Numerical results of wave propagation influenced by the HIP joints with and without defect explain response of the receiver signals. These results suggest a possibility of the HIP joint inspection by using EMATs.
