​ULTRASONIC THICKNESS/FLAW DETECTION (LONGITUDINAL)
Ultrasonic testing (UT) is a family of ​non-destructive testing​ techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion.

 ULTRASONIC SHEAR-WAVE (ANGLE BEAM)

Picture
Angle beam transducers are used in conjunction with plastic or epoxy wedges (angle beams) to introduce shear waves or longitudinal waves into a test piece at a designated angle with respect to the surface. They are commonly used in weld inspection. ​

PHASED ARRAY

Phased array ultrasonic testing (PAUT) is an advanced method of ultrasonic testing.  In contrast, the beam from a phased array probe can be focused and swept electronically without moving the probe. The beam is controllable because a phased array probe is made up of multiple small elements, each of which can be pulsed individually at a computer-calculated timing. The term phased refers to the timing, and the term array refers to the multiple elements.
