Sonic-IR which is based on the thermographic detection of the temperature rise due to frictional heating at the crack faces unde r ultrasonic excitation, has an advantage in the detection of closed cracks. Additionally, there is possibility to apply this te chnique to the inspection of complex geometry components because it is nearly non-contact technique. In this study, feasibility of the Sonic-IR technique for the detection of weld cracking is experimentally investigated by using small bore piping specimens.
