Abstract
PURPOSE: To enable to obtain function of failure detection in water the same as on land, by filling the inspection liquid including mangnetic powder in the inspection cassette made of transparent seal vessel.
CONSTITUTION: Afterstalling the inspection cassette 10 on the surface of the inspected construction object 4, magnetization is made by flowing current from the power supply 2 of magnetization unit to the magnetizer 1, the magnetic flux 7 is disturbed at the failure part 8, the leakage magnetic flux reaches inside the inspection cassette 10 via the non-conductive elastic thin film 10b, and sharp magnetic powder pattern is drawn on the non-conductive elastic thin film 10b with the magnetic powder 5 not subject to the effect of external water flow. The failure part can be detected with this pattern.
