Apparatus for magnetic particle inspection with an adjustable cable for magnetizing inspection areas of variable dimensions

Abstract: A magnetic particle inspection system includes apparatus for applying a magnetic field to an inspection area of a metal structure. This apparatus comprises a power cable arranged in at least one cable inspection loop to which electrical power is connected. In this way the adjacent inspection area is magnetized. The inspection aea is sprayed with disclosing fluid and an ultra violet light illuminates the sprayed area. The length of the cable inspection loop is adjustable so that the area of the inspection area can be varied. The apparatus is particularly designed to be mounted on a remotely operated vehicle.
