摘要

Maintenance of aging infrastructure facilities in urban area is a critical issue. Actually, in Kobe city, two illumination pillars fell down because they had corrosion under the ground line. This study aims to detect corrosion of illumination pillars using ultrasonic guided wave generated by electromagnetic acoustic transducer (EMAT). The guided wave is expected as a quick and long distance inspection technology for piping systems. In this study, a guided wave inspection system using the EMATs is proposed. The guided wave inspection system detects corrosion by reflected waves from corrosion. The effectiveness of the proposed system for screening of corrosion in illumination pillars is verified through experiments using both retired and active illumination pillars.
