Eddy Current Pulsed Thermography(ECPT) is a developed technique in Non-Destructive Testing and Evaluation (NDT&E). It is widely used in detecting metal surface and sub-surface defects. In the present researches, many thermal feature extraction methods have been used to achieve more valuable hidden information. At the same time, a quantitative analysis strategy is proposed for determining the size of the defection based on Eddy Current Pulsed Thermography. In this paper, the Q235 was selected as the analysis materials, with multiple surface defects detection, was studied by using eddy current pulsed thermography. Based on the theoretical and experimental studies, the results show that the pulsed eddy current thermal imaging technology can detect the different position defects both on the qualitative and the quantitative evaluation effectively. It can serve as guidelines to improve the visibility and detectability of defects with different defects in the future. [ABSTRACT FROM AUTHOR] |
