Nondestructive Testing of Metal Parts by Using Infrared Camera

Abstract The paper deals with non-destructive testing of metal parts excited by ultrasound. Material response to this excitation is detected by infrared camera. Damages in the material, such as crakes and cavities are identified based on temperature changes detected by infrared camera. The paper presents detection of cracks on the real steel form used in the production of aluminium castings when cracks resulting from thermal fatigue. There are also discussed some problems associated with the using of this technology.
