Several False Defect Signals in Acoustic Emission Testing of Pressure Vessels
Several false defect signals in acoustic emission of pressure vessel like the vibration noise, electromagnetic noise, corrode outcome splitting and the friction between backing board were introduced. Frequency analysis of these signals was conducted. So the signals could be distinguished by frequency.
