Patent ID: 8823369

Claim:
An inspection system for detecting defects in a bore of a component, said system comprising: an inspection device configured to be inserted into the bore, said inspection device including a core made of a ferromagnetic material, a first coil wound around the core in a first direction and a second coil wound around the core in a second direction, where the first and second directions are orthogonal to each other; a protective material that encases the core, the first coil and the second coil; and a controller programmed to control the inspection device, said controller selectively providing a current flow in the first coil and the second coil when the inspection device is within the bore to generate electromagnetic fields in orthogonal directions within the bore to detect the defects therein, wherein the current flow is selectively provided to detect surface defects and deep structure defects in directions that are transverse and longitudinal relative to the bore.
