PAUT
Phased Array Ultrasonic Testing (PAUT)
- Phased Array Ultrasonic Testing is an advanced non-destructive testing (NDT) technique that uses multiple ultrasonic elements and electronic time delays to steer, focus, and scan beams. This allows for highly detailed inspection of materials without causing damage—ideal for detecting internal flaws, measuring thickness, and evaluating weld integrity.
- A probe with multiple transducer elements emits ultrasonic waves.
- Electronic control adjusts the timing of each element to steer and focus the beam.
- The system generates real-time images of the internal structure, revealing cracks, voids, and other discontinuities.
PAUT is used across industries for:
- Weld inspection (butt welds, fillet welds, overlays)
- Corrosion mapping
- Flaw detection in complex geometries
- Composite material evaluation
- In-service inspections of pressure vessels and pipelines
