What is the method?
PAUT is an advanced ultrasonic method using multi-element probes to electronically steer, focus, and sweep the sound beam through the material. It produces image-based inspection data such as S-scans and C-scans.
Application
PAUT is an advanced ultrasonic method using multi-element probes to electronically steer, focus, and sweep the sound beam through the material. It produces image-based inspection data such as S-scans and C-scans.
Key Benefits
- Enhanced coverage compared with conventional UT.
- Image-based inspection data.
- Improved defect positioning and characterisation.
- Suitable for complex weld geometries and critical applications.
Inspection Capabilities
- Electronically scans through multiple angles from one probe position, improving weld coverage.
- Particularly effective for complex weld geometries, nozzle intersections, and unfavourably oriented flaws.
- Supports improved defect imaging, interpretation, and reporting.
- Can consolidate multiple conventional angle-beam inspections into one scan plan.
Limitations
- Requires specialised equipment and skilled personnel.
- More complex setup and interpretation than conventional UT.
- Surface condition affects coupling and data quality.
- Often combined with ToFD or other methods for full assessment.
