Course Description:
This method employs high frequency sound pulses that are emitted from a transducer; this sound wave is induced in to the material through a probe which is usually in contact with the material.
These sound waves propagate through the material, and are reflected back to the probe when they reach an interface, the reflected waves are transmitted back through the probe and connecting leads to a detector which can either analogue or digital. The sounds waves are then displayed as a series of signals on a monitor and the qualified inspector can measure. and interpret these signals to allow accurate evaluation of the material.
Ultrasonic testing can not only be used to indicate a surface or subsurface flaw. It can also be used to determine the depth, size and type of flaw. Another advantage of using UT is the accurate measurement of the thickness of the material. The method can be applied to most materials providing the material can transmit sound waves. UT is considered to be a fast and effective way of inspection providing highly sensitive results.
