Steel-billets can be checked for cracks automatically at transportation velocities of up to 1.5m/s by inductive excitation.defectovision-ir-freisteller-001_web

A coil induces an electrical crisspruefung-im-durchlauf_1urrent with high frequency in the region close to the surface of the billet. If there is a crack located in the path of the electrical current, more heat is produced at the crack tips and flanks. A thermal camera is viewing the surface temperature, and an evaluation unit searches for hot spots, which indicates a crack.

In harsh industrial environment, the thermal data can contain some noise, which could look similar to a crack signal. To suppress false display, the temporal evolution is also evaluated. With this method, cracks can be identified, and robust and stable results will be displayed.
