Acoustic Emission Testing
Acoustic Emission (AE) is a nondestructive testing method used for monitoring structures or components to detect actively propagating flaws. By applying stresses to a test specimen, an active flaw will release acoustic energy as an elastic waveform which is detected, located, and characterized by the AE system developed by Vallen
Systeme.

- AE is a global monitoring technique. That is an entire structure can be
monitored from a few locations.
- Most of the time the equipment can be monitored while in service with
little interruption to the normal process.
- There is typically less time and less cost than other NDE methods due to test an entire structure in only one test. Also, there is only the need to remove insulation from small predetermined areas, rather then clearing the entire strucutre.
- Detects only active defects. Dormant or inactive defects are not detected.
- If areas are detected in the AE testing, only those areas and not the entire structure need to be
followed up by other traditional NDE methods
