Ultrasonic Testing and Thickness Measurement

This common method of NDT inspection utilises high frequency mechanical energy in the form of sound waves. It is able to detect internal, hidden discontinuities and has a wide range of applications from thin sheet steel through to large cast components.

Ultrasonic Flaw Detection (UT)

Used to detect internal discontinuities within a weld such as inclusions, porosity, cracks, lack of fusion etc. Utilising Ultrasonic flaw detection techniques, SST-NDT are able to provide the discontinuity location, size, orientation and features ensuring correct analysis.

This inspection technique is frequently used within the fabrication industry for quality control of new welds as well as ensuring the integrity of in-service weldments and components throughout multiple industries.

Ultrasonic Thickness Gauging / Measurement (UTG / UTM)

A non-destructive testing method used to inspect the thickness of a material of component. An ultrasonic thickness gauge works by measuring how long it takes for a sound pulse to travel through a material and reflect from in internal surface, this is then displayed on a digital screen.

This commonly used method can be applied to a wide range of structures and components such as ship hulls, piping and pressure vessels and structural steel.
