Aims at the safety problems caused by corrosion under coating for it can not easily be observed, specimen of corrosion damage under coating was made for the research of detection by applying infrared thermal wave technology. The surface temperature distribution infrared thermal images were captured, also the surface temperature history of corrosion area, non-corrosion area and their difference. Analysis of test results show that the infrared thermal wave technology is an effective tool in detecting corrosion damage under coating, there has a fine detection time used to estimate the coating thickness, and the position and sizes of defects can be found out directly by the hot spots in the infrared images. The damages can be quantitatively recognized by images processing, but surface uniformity of the specimen has great impact on the damage identification.

Glass Curtain Wall

Adhesive bonded structure damage of hidden frame glass curtain wall will cause falling glass, which threatens the security of people and property. Therefore, the damage detection of the adhesive bonded structure of glass curtain wall has great significance. In this paper, active thermal sensing technology for bonding structure damage detection was introduced. Firstly, the thermal wave propagation of bonded structure was analyzed. Second, the simulated annealing algorithm and TracePro simulation were utilized to design the heat source. Thirdly, the platform of active thermal sensing was built, and experiments were conducted. Finally, image fusion enhancement of Laplacian pyramid was utilized to the enhancement process of thermal images. The simulation results showed that the irradiance of the cross-optimization was more uniform, and the uniformity was 17.50% higher than the original design value. The experiments results showed that defects of different sizes and depths can be distinguished. The gray differences of the damages on the depth of 0 mm and 4 mm were 0.025 and 0.045, respectively. The thermal wave testing can detect damage intuitively and rapidly, which is significant for the future research of unmanned detection of bonding structure damage of hidden frame glass curtain wall.
