Phased Array Ultrasonic Testing Units for Advanced Flaw Detection
High-resolution PAUT systems offering multi-angle inspection, rapid scanning, and reliable defect characterization
Overview
Phased Array Ultrasonic Testing (PAUT) units revolutionize flaw detection and material evaluation by using multiple elements in a single probe to steer, focus, and scan ultrasonic beams electronically. This advanced NDT method allows for precise imaging of internal structures at multiple angles without repositioning the probe. PAUT systems offer faster, more detailed inspections than conventional ultrasonic tools and are ideal for complex geometries, welds, and layered materials.
This page offers a complete guide to phased array ultrasonic testing technology, including its powerful features, industry applications, and system integrations.

Case Studies
United States
Long-Seam Weld Inspection – Pipeline Operator, Bismarck, ND
A major pipeline company used GAO Tek’s portable phased array units to inspect long-seam welds during a rehabilitation project. The system identified subsurface cracking with precision, avoiding costly rework and ensuring code compliance.
United States
Aerospace Panel Integrity Testing – Aircraft OEM, Mobile, AL
Technicians employed PAUT systems to scan curved composite panels for delamination and foreign inclusions. The phased array’s beam steering and real-time imaging reduced test time and improved detection accuracy across complex geometries.
Canada
Corrosion Mapping – Refinery Storage Tanks, Edmonton
A Canadian refinery implemented phased array corrosion mapping to monitor tank wall thinning. Acoustic Testing Pro’s system produced high-resolution C-scans, enabling prioritized maintenance and minimizing asset downtime.
