2 MHz Ultrasonic Transducer Probe High Angle Creep Ultrasonic Longitudinal Waves

Creep Waves Probe,ultrasonic probe transducer with high angle ultrasonic longitudinal waves

The maximum working range is typically 45 mm in front of the probe because
the creep wave rapidly loses energy in the form of 33º indirect shear, or &39;head&39;, waves as it propagates. However, these head waves will
re-convert to a creep wave at the inner surface of the component. Like the top
surface creep wave, this inner surface creep wave is very sensitive to inner
surface breaking cracks and as it runs parallel to the inner surface it will not be sensitive to the presence of weld roots.

Creep waves have the advantage that, being longitudinal waves, they are far
less attenuated in austenitic and inconel weld metal than shear waves.
