Acoustic Emmission Testing
Acoustic emission (AE) is the phenomenon of radiation of acoustic (elastic) waves in solids that occurs when a material undergoes irreversible changes in its internal structure. These changes can result from processes like crack formation, plastic deformation, or aging. When a structure is subjected to an external stimulus (change in pressure, load, or temperature), localized sources trigger the release of energy, in the form of stress waves, which propagate to the surface and are recorded by sensors. This occurs when a small surface displacement of a material is produced.
TCR Advanced has procured state of the art 16 channel AE System form Vallen Systeme, Germany. TCR has experienced technicians and Advance softwares to interpret Data to accurately identify flaws of critical jobs with accuracy.The main advantage of Acoustic Emission testing is fast and complete volumetric inspection using multiple sensors, permanent sensor mounting for process control, and no need to disassemble and clean a specimen.
Advantages of Acoustic Emmission TEsting:
- High sensitivity.
- Early and rapid detection of defects, flaws
- Identifiaton of Crack growth
- Real time monitoring.
- Cost reduction
- Minimization of plant downtime for inspection, no need for scanning the whole structural surface.
