The application of infrared (IR) thermography for detecting defects under the surface as well as for the estimation of the corrosion intensity seems to have good prospects as a non-destructive testing method. Besides the limitations which are the result of the IR camera itself and the thermal properties of the material detected, IR thermography produces acceptable results when combined with an appropriate numerical method. A numerical simulation of heat transport makes possible a separate analysis of the relevant parameters that characterize heat dissipation in the material, like the intensity and duration of the heat stimulation, the properties of the material and the starting conditions, as well as the time distribution of certain parameters. The comparison of a numerical simulation and thermographic measurements presented in [5] shows a very good agreement of the results. The importance of determining the moment when the contrast reaches its maximum can be clearly seen from the numerical analysis. The analysis also shows that a relative material loss and the diameter of the defect can be estimated with the best accuracy at the moment when the current contrast reaches its maximum.
