V2 Ultrasonic Calibration Block

V2 Calibration Block is designed for verification of the ultrasonic flaw detectors used in the course of welded joints quality control by the UT method. It is DSTU 4002-2000 (ISO 7963, В.S.2704) compliant.

V2 Calibration Block allows:

• to calibrate the sweep of the flaw detector by the ultrasonic wave velocity for the straight beam piezoelectric transducers
• to calibrate the sweep of the flaw detector by the ultrasonic wave velocity for the angle beam piezoelectric transducers
• to set a conditional level of sensitivity of the UT flaw detectors with the straight and angle beam transducers
• to determine the probe index and X-value of the angle beam transducers
• to determine the UT wave entry angle in steel.
