Phased Array Ultrasonic Testing (PAUT) Services
Phased Array UT uses multi-element transducers to electronically steer and focus ultrasonic beams for advanced imaging.
What is Phased Array Ultrasonic Testing?
Phased Array Ultrasonic Testing (PAUT) is an advanced UT technique that uses multi-element transducers controlled electronically to generate focused beams that can be steered, scanned, and swept without mechanical movement. This enables real-time imaging of cross-sections, faster scanning speeds, and more reliable detection compared to conventional UT.
How PAUT Works
Multiple transducer elements fired with controlled time delays
Electronic beam steering and focusing
Sectorial (S-scan) and linear (L-scan) imaging
Real-time cross-sectional visualization
