Phonon
Emission

The result of interaction of energy and material causes various physical processes taking place in the material: stress concentration, deformation, corrosion, fatigue damage and deterioration. Phonon energy is emitted at areas of defect formation growth and phonon detection is collected through state-of-the-art transducers which are attached to the inspected asset.

PDT inspection consists of data acquisition, processing, analyzing and interpreting defect characteristics based on phonon emission propagation.

PDT INSPECTION STEPS

1. PREPARATION
Obtaining information that will be used to design the asset mathematical modelling, selection of configuration, pre-setting and theoretical calibration, mobilization of PDT specialist and equipment.
2. PRE-PHONON
Performing equipment calibration, geometric physical measurement, material thickness profiling and closed visual inspection based on relevant code and standard.
3. PHONON MONITORING
Real-time data acquisition using phonon equipment.
4. POST-PHONON
Processing and analysis of the gathered data and final report preparation.
