Case Studies
United States
Composite Bond Inspection, Seattle WA
A major aerospace contractor used our air-coupled ultrasonic probes to validate adhesive bonding in carbon fiber fuselage panels. Non-contact scanning enabled testing without damaging protective films or coatings, reducing rework and boosting throughput.
United States
Inline Quality Control,
Detroit MI
An EV manufacturer integrated our air-coupled ultrasonic sensors into a robotic QC station for laminate inspection. Automated waveform analysis identified flaws in under 2 seconds per part, improving inspection speed, consistency, and traceability.
Canada
Cultural Heritage Preservation, Toronto
A leading museum partnered with Acoustic Testing Pro to examine wooden and layered artifacts for internal flaws. Our non-invasive ultrasonic solution detected delamination without disturbing surfaces, supporting targeted conservation work.
