Acoustic Emission Testing (AE) Services
Acoustic Emission Testing monitors structures in real-time by detecting stress waves emitted from growing defects.
What is Acoustic Emission Testing?
Acoustic Emission Testing (AE/AET) is a passive NDT method that detects elastic waves generated by the rapid release of energy from growing defects, corrosion, or leaks within a structure. Multiple sensors placed on the structure detect and locate emission sources in real-time, providing continuous structural health monitoring capability.
How AE Works
Sensors detect elastic waves from active defect sources
Triangulation locates emission sources
Real-time monitoring of structural integrity
Passive method - structure must be under load
Applications of Acoustic Emission Testing
Advantages
- Real-time monitoring capability
- Global inspection from sensor array
- Detects active/growing defects
- Continuous structural health monitoring
- Can inspect during operation
- Identifies critically stressed areas
Limitations
- Only detects active/growing defects
- Requires loading or operation
- Environmental noise interference
- Complex data interpretation
- Specialized equipment and training
- Cannot determine defect size directly
