Acoustic Emission (AE)

Πληροφορίες

The method of Acoustic Emission (AE) is one of the newest techniques in the industry of NDT, which is using transient elastic waves that are created from the rapid release of energy from localized sources within a material.

In the specific method appropriate piezoelectric transducers are used in order to convert the transient elastic waves into electrical signals.

The gives the NDT operator the ability to inspect large surfaces and constructions , detect discontinuities in areas with limited access and are applicable at any stage, even during the manufacturing process.

However, Acoustic Emission pulses are not generated from all the types of defects that might exist within a material. Moreover, the efficacy of the method depends on the charging method of the component that is inspected. The existence of noise can adversely affect the results of the inspection procedure.
