Internal SCC Detection of Pipe Using Ultrasonic Infrared Thermography

Abstract

This study detected internal PWSCC of DMW( STS304 Pipe and SA106 Gr. b) pipes using the ultrasound infrared thermography Method and the lock-In image process method among infrared thermography method. An ultrasonic wave generator of 20 kHz oscillation frequency was made utilizing this characteristic and the experiment was conducted with 250 Watt output… (More)
