PCN Training Curriculum

Ultrasonic Testing (UT)

What is Ultrasonic Testing?

Ultrasonic is a high frequency of sound pulses that are emitted from a transducer above a sample. The sound waves propagate through the sample, and reflect at interfaces. The reflected waves are monitored using a detector above the sample. The thickness of the sample, and the depth and type of flaw can be ascertained using this method. The method can be applied to most materials if sound transmission is good. Quick high sensitive results are obtained.

For Level II

What is Ultrasonic Phased Array?

Phased Array technology is the ability to modify electronically the acoustic probe characteristics. Probe modifications are performed by introducing time shifts in the signals sent to and received from individual elements of an array probe. Any Ultrasonic techniques for flaw detection and sizing can be applied using Phased-Array probes.

Phased Array provides high speed electronic scanning without moving parts, improved inspection capabilities through software control of beam characteristics, inspection with multiple angles with a single electronically controlled probe, many configurations; P/E, T/R, TOFD and Tandem, and greater flexibility for inspection of complex geometries (optimized focusing and optimised beam angle).

Phased Array can be used for the following applications; raw material production, aircraft, naval, power generation, petrochemical and anything else that currently applies pulse-echo testing.
