Apparatus and method for nondestructive inspection

摘要

A nondestructive inspection apparatus according to the present invention has a transmission-side probe configured to emit a first ultrasonic wave toward a test-target fluid, a plate through which a Lamb wave generated by the first ultrasonic wave is propagated when the first ultrasonic wave is propagated, and a reception-side probe configured to measure intensity of a second ultrasonic wave which is emitted from the plate and propagates through the test-target fluid. At this time, the nondestructive inspection apparatus can inspect the test-target fluid without bringing the transmission-side probe configured to emit the first ultrasonic wave and the reception-side probe configured to measure the second ultrasonic wave into contact with the test-target fluid.

主权项

1. A nondestructive inspection apparatus comprising:
a plate for supporting a test-target fluid; a transmission-side probe disposed on one side of the plate and arranged such that the test-target fluid will be between the plate and the transmission-side probe, the transmission-side probe being configured to emit a first ultrasonic wave toward the test fluid; a reception-side probe disposed on the one side of the plate and arranged such that the test-target fluid will be between the plate and the reception-side probe, wherein the plate is configured to generate a Lamb wave based on the first ultrasonic wave propagated through the test-target fluid and propagate the Lamb wave to another portion of the plate, and to generate a second ultrasonic wave based on the Lamb wave and propagate the second ultrasonic wave to the test-target fluid, the reception-side probe is configured and arranged to receive the second ultrasonic wave propagated through the test-target fluid and measure intensity of the second ultrasonic wave, and the transmission-side probe and the reception-side probe are not in contact with any liquid including the test-target fluid.
