Comparing the passive and active thermographic images, the passive thermographic image didn’t show the location of blistering zones. However, the active thermographic image definitely appeared locations, shapes and sizes of blistering zones since the heating. This study focused on drawing the temperature curve, calculating the critical temperature, and establishing the transitional zone of blistering zone using final image among five active thermographic images in Figure 2. The critical temperature is to quantitatively differentiate between fresh and blistering zones, and is favorable to measure on a spot from the inside of blistering, where fresh zone gradually turn into blistering zone, more than a spot, where blistering crack is detectable with naked eye. The reason is that the blistering crack causes rapid temperature changes.

Hi there, Sir [이름]! Thanks for your composition. The vocabularies are quite complicated because I am not familiar with your study. Nevertheless, I did my best to correct them for you. take care and have a nice day! T.
