Measurement of Faulty Penetration Actual Height in Unilateral Butt Welded Connections with the help of Ultrasonic Flaw Detectors with Antenna Arrays

Butt welded samples have been tested by ultrasonic flaw detector with antenna array and then opened; testing results are received. Specifics of signal acoustic image interpretation are specified. The method of measuring of faulty penetration height in butt welded connections based on distance between signals (focal spots amplitudes) is considered.
