Paper Abstract

Pulsed-heating infrared thermography non-destructive testing is one of the most common used technology in industial NDT/NDE. It has an advantage on simple instrument and easy operation among method for NDT/NDE. To get an persuasive result, properties of heating pulse should be adjusted to testing condition, such as depth of defect and thermal conductivity of material. This paper tries to derive a method for optimization of heating pulse. The method is based on theory of thermal wave. The pulse should be chosen to make itself contain more effective thermal frequency components for NDT. The effect of this method can be verified by simulation and NDT experiments in this paper.
