| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have developed a non-contact thickness gauging equipment for underwater steel structures such as steel pipe piles of the pier. Efficiency of non-contact measurement is better than that of conventional contact measurement for inspection work. The measurement principle is as follows. We use the convergence transducer of large diameter in order to focus ultrasonic waves on the inside the steel plates.We measure the time intervals of multiple reflections from the steel plate, and calculate the thickness using the measured values.Sufficient results were obtained in field experiments. |
