Load-Induced Acoustic Emission Analysis
Acoustic emission analysis under load registers sound waves generated by mechanical stress. It enables real-time monitoring of cracks and deformations.
Physical-Chemical Mechanism of Action
Acoustic emission analysis under load (SEA) measures sound waves generated by sudden plastic deformation or crack propagation under mechanical stress. These waves are captured by a piezoelectric sensor and analyzed in real time.
Metallurgical Relevance & Welding Risks
SEA is especially important for monitoring weld integrity under load. It can detect cracks or deformations early, before they become visible. Missing or inaccurate measurements can lead to overlooked defects that may later cause structural failure or safety issues.
Workshop Practice & Action Instructions
For accurate SEA under load, a special measurement system with a piezoelectric sensor is used. The sensor must be correctly mounted and calibrated. Measurement should be done during mechanical loading to capture actual sound waves. If unusual or unexpected acoustic patterns occur, inspect the components immediately.
