Abstract: Air-coupled ultrasonic testing has wide-developing prospects for the characteristics of non-contact, non-invasive, non-damage, which can be better used in ultrasonic testing situations where traditional ultrasonic testing is difficult to adapt. This paper gives the systemic overview on the air-coupling ultrasonic testing technology research status and introduces the current research progess of piezoelectric type transducer and the current successfully applied signal processing technology. We also briefly analyzes and introduces the hot research area and progress of the air-couple ultrasonic testing. Finally, We discuss the development trend of air-coupled ultrasonic testing and application prospect.

Key words: air coupling, transducer, signal processing, ultrasonic testing
