The basic principles of ultrasonic testing involve the propagation and reflection of sound waves. This 8-minute, 14-second video shows how defects and abnormalities can be detected using the pulse-echo method. Watch animations of longitudinal sound waves propagated and reflected through a cylindrical workpiece as well as an actual ultrasonic inspection of a wheel axle to gain a better understanding of this type of nondestructive testing.
