Non-destructive evaluation system of metal materials according to thermal behaviours

The infrared thermography non-destructive inspection technique is a quality inspection and stability assessment method, which was used to diagnose the physical characteristics and defects by detecting the infrared ray radiated from the object without destructing it. The technique is being applied to diverse sectors. Its usage and importance increase with the development of the industrial areas that require high reliability and stability, including the semiconductor, nuclear power, defense, aerospace, and car industries. In this research, Ultrasound infrared thermography non-destructive evaluation system for metal materials according to thermal behaviours is established. To build ultrasound infrared thermography inspection system, infrared thermography test was performed by optimal design of the ultrasound excitation device and external energy control.
