    Using EMAT, the requirements to surface smoothness are less stringent; the only requirement is to remove loose scale and the like. Easier for sensor deployment. Using piezoelectric transducer, the wave propagation angle in the test part is affected by Snell's law. As a result, a small variation in sensor deployment may cause a significant ...

  9. Phased array ultrasonics - Wikipedia

    en.wikipedia.org/wiki/Phased_array_ultrasonics

    At a construction site, a technician tests a pipeline weld for defects using an ultrasonic phased array instrument. The scanner, which consists of a frame with magnetic wheels, holds the probe in contact with the pipe by a spring. The wet area is the ultrasonic couplant that allows the sound to pass into the pipe wall.
