Keywords:electromagnetic acoustic transducer, pipe wall thinning, monitoring

In this study, pipe wall thinning is monitored by electromagnetic acoustic resonance method during the corrosion test of a pipe. Analyising the resonance waveforms, time evolution of pipe wall thickness is estimated. In addtion, accruracy and reliability of measurement are confirmed.
