Abstract: Ultrasonic infrared thermography is a nondestructive testing method with significant research value and has the advantages of selective heating and detection of complex workpiece cracks. We introduce the principles and system composition of ultrasonic infrared thermography technology, and its development history and current situation in China is reviewed and summarized. The status of simulation research, composite material damage, fatigue crack, metal component crack, and concrete parts crack in application fields is discussed in detail. Finally, future development trends in ultrasonic infrared thermography technology are discussed.
