Advanced Phased Array Ultrasonic Probes for High-Resolution Inspection

Multi-element ultrasonic probes for precise flaw detection, weld evaluation, and volumetric scanning across complex geometries

Overview

Phased array ultrasonic probes (PAUT) represent a breakthrough in non-destructive testing by enabling highly accurate, real-time imaging of internal flaws and structural inconsistencies. These probes use multiple piezoelectric elements that can be electronically controlled to steer, focus, and scan ultrasonic beams through materials—without moving the probe itself. This flexibility delivers exceptional results for weld inspection, corrosion mapping, and complex shape evaluation.

This webpage explores the benefits, configurations, and industrial applications of phased array ultrasonic probes. Acoustic Testing Pro proudly supports clients across North America with high-performance, application-specific PAUT solutions that improve detection accuracy, reduce inspection time, and meet critical safety standards. Whether in aerospace, energy, construction, or research, our systems empower technicians and engineers to perform smarter, faster, and more comprehensive inspections.

Case Studies

United States

High-Pressure Pipeline Weld Testing, Oklahoma

A pipeline contractor used our 64-element phased array system to inspect girth welds. PAUT allowed full volumetric weld evaluation in minutes per joint, reducing inspection costs by 40%.

United States

Wind Turbine Blade Quality Assurance, Colorado

A renewable energy firm applied our PAUT wedge probe system to evaluate composite layers in turbine blades. Early flaw detection helped reduce warranty claims and extend service life.

Canada

Nuclear Steam Generator Tube Assessment, Ontario

Our phased array probes and RFID-enabled DAQ tools were deployed to inspect heat exchanger tubes at a Canadian nuclear plant. The system passed CSA W178.1 audits and improved historical data traceability.
