Project Objectives

The automated system of thermographic crack detection is based on the physical phenomenon of the electromagnetic induction, a far know - yet very powerful - technique that was first developed as a thermal treatment for the hardening of metallic components.

An alternate current generator provides an oscillating current at a specified frequency, flowing into a conductive coil which is shaped such mirroring the train wheel. The coil is positioned as close to the wheel as possible and the varying magnetic field in its cross-section produces an electric field in the metallic material of the wheel.
