Teaching Industrial Echography

In ultrasonic testing, very short ultrasonic pulse-waves with

centre frequencies ranging from 0.1-15 MHz are launched

into materials to detect internal flaws or to characterize

materials. The technique is also commonly used to determine

the thickness of the test object, for example, to monitor pipe

work corrosion.

Ultrasonic testing is often performed on metals and alloys,

though it can also be used on concrete, wood and composites.

It is used in many industries including oil & gas, aerospace,

automotive and other transportation sectors.

The experimentation sets for industrial echography focus on

the understanding of the observed signals and images in the

context of Non Destructive Testing (NDT). Also the limitation of

the technique as a consequence of physical properties and

fundamental physical laws is investigated. For this different test

samples and setups including delay lines, different material, and

blocks with specific discontinuities are used. Additionally the

ultrasound is used to demonstrate mechanical scan methods

and the principle and formation of computer tomography.
