Abstract

Work on three thermographic NDE techniques that have been developed to locate and image cracks in metallic components is reviewed. These techniques are: thermosonics (sonic IR, ultrasonically stimulated thermography); laser spot thermographic imaging; and pulsed eddy current stimulated thermography. The three techniques are explained and examples are given of their performance in imaging well-characterised cracks. Factors concerning the practical and reliable implementation of the techniques are discussed.
