Infrared testing

Infrared thermography is one of several non-destructive testing techniques which can be used for surface or near subsurface defect or crack detection. Infrared thermography is a technique of producing a live thermal picture of an object based on the infrared radiation received from it (emitted by any object). In pulse thermography, a thermal pulse is applied to the material to be inspected.

Cracks, if present, will disturb the current flow and so generate changes in the temperature profile in the crack area. These changes of temperature are visualized using an infrared camera.
