PHASED ARRAY ULTRASONIC INSPECTION (PAUT)
PHASED ARRAY ULTRASONIC INSPECTION (PAUT)
PAUT - Applications
- Corrosion Mapping
- Weld Inspections
- Thickness measurements
- Flaw Detection
PAUT - Advantages
- PAUT is an Advanced ultrasonic technique
- PAUT can be over 4x faster than regular “A Scan” ultrasonic weld inspection & has an increased probability of detection
- Scan data can be encoded for immediate defect characterisation and accurate length and height sizing.
- Permanent records of scan data files can be stored for traceability and auditing.
- Often used as a substitute for radiographic and manual UT examinations
- We have the latest Omniscan X4 PAUT set released in 2024 with all the latest capabilities such as Phase Coherence Imaging (PCI) & 3x faster Total Focussing Method (TFM) acquisition rate.
- New Phase Coherence Imaging (PCI) test method, great for detecting High Temperature Hydrogen Attack (HTHA), volumetric defects, and for through wall height sizing using tip diffraction.
Example of encoded PAUT scan with lack of side wall fusion, sizing for length and thru-wall height
