Application of Laser-Generated Ultrasound for Evaluation of Thickness Reduction in Carbon Steel Pipes
In carbon steel pipes of nuclear power plants, local wall thinning may result from erosion-corrosion or flow-accelerated corrosion(FAC) damage. Local wall thinning is one of the major causes for the structural fracture of these pipes. Therefore, assessment of local wall thinning due to corrosion is...

| description | In carbon steel pipes of nuclear power plants, local wall thinning may result from
erosion-corrosion or flow-accelerated corrosion(FAC) damage. Local wall thinning is one of the
major causes for the structural fracture of these pipes. Therefore, assessment of local wall thinning
due to corrosion is an important issue in nondestructive evaluation for the integrity of nuclear power
plants. In this study, laser-generated ultrasound technique was employed to evaluate local wall
thinning due to corrosion. Guided waves were generated in the thermoelastic regime using a
Q-switched pulsed Nd:YAG laser with a linear slit array. . In this paper, time-frequency analysis of
ultrasonic waveforms using wavelet transform allowed the identification of generated guided wave
modes by comparison with the theoretical dispersion curves. Modes conversion and group velocity
were employed to detect thickness reduction. |
