A Comparative Study on Thermal Excitations of Thermographic Defect Inspection and Identification

JIA Wen-dou;FAN Chun-li;SUN Feng-rui;YANG Li;College of Power Engineering, Naval University of Engineering;  
A good selection of thermal excitations is crucial to the active thermographic defect detection and identification work. A two-dimensional heat conduction model with inner defects was built in this paper to analyze the temperature distribution rules on the inspection surface. The applying way of thermal excitations was altered by changing the heating area, heating position and heating heat flux. The temperature distribution on the inspection surface of the test-piece was analyzed. It is found that better identification heating effect can be obtained when multiple boundaries with thermal excitation applied are adjacent.
