The 12th European conference on non-destructive testing was held in Gothenburg, Sweden, in June 2008. The conference brought together non-destructive testing technicians from all over the world to exchange the latest development and application of non-destructive testing technology in different fields. Components in the aerospace field often have the characteristics of complex surface structure and material properties, which makes it difficult for traditional ultrasonic testing methods to effectively evaluate the internal defects. Aiming at the research and application status of ultrasonic nondestructive testing technology in aerospace field, the latest research and development achievements of ultrasonic array, aircoupled ultrasonic and laser ultrasonic et al are introduced. The future development direction and trend of advanced ultrasonic testing technology in aerospace field are discussed. The key technologies and research difficulties of current ultrasonic testing technology are summarized.
