• Problem: Battery tray welds required fast, repeatable inspection during high-volume production.

• Solution: Conveyor-integrated Automated Ultrasonic Testing Systems performed inline weld inspection using synchronized encoders.

• Result: Inspection kept pace with production throughput without adding labor.

• Lesson: Inline AUT must be synchronized precisely with conveyor speeds to avoid scan gaps.

Implementation Case – Wind Turbine Shaft Inspection, Des Moines, Iowa

• Problem: Large turbine shafts required complete volumetric inspection before field deployment.

• Solution: A gantry robotic ultrasonic system scanned shafts using multi-axis motion control.

• Result: Full volumetric mapping completed before shipment, reducing field failures.

• Lesson: Large geometry inspection requires careful probe angle optimization.

Implementation Case – Ship Hull Weld Inspection, Norfolk, Virginia

• Problem: Hull weld testing in shipyards was labor-intensive and inconsistent across shifts.

• Solution: A mobile automated ultrasonic testing platform adapted to vertical and horizontal weld paths.

• Result: Consistent weld evaluation independent of operator skill.

• Lesson: Environmental moisture and surface coatings affect coupling quality.

Implementation Case – Nuclear Component Fabrication, Oak Ridge, Tennessee

• Problem: Nuclear components required repeatable inspection aligned with regulatory documentation.

• Solution: Automated UT integrated with inspection databases and reporting systems aligned with ASTM E2373.

• Result: Inspection traceability improved for regulatory audits.

• Lesson: System validation is as important as hardware performance in regulated sectors.

Implementation Case – Steel Plate Lamination Detection, Pittsburgh, Pennsylvania

• Problem: Manual inspection missed internal laminations in thick steel plates.

• Solution: Gantry-based automated ultrasonic scanning with C-scan imaging across plate surfaces.

• Result: Early lamination detection before shipment.

• Lesson: Flat surface scanning benefits most from automated raster motion.

Implementation Case – Aircraft Landing Gear Forging, Wichita, Kansas

• Problem: Complex forged geometries made manual probe placement unreliable.

• Solution: Robotic AUT with pre-programmed probe paths for geometric consistency.

• Result: Consistent subsurface detection across parts.

• Lesson: Probe alignment tooling is critical for repeatability.

• Result: Inspection throughput improved before offshore deployment.

• Lesson: Portability requires trade-offs in gantry rigidity.

Implementation Case – Heavy Casting Inspection, Birmingham, Alabama

• Problem: Casting porosity detection was inconsistent with manual methods.

• Solution: Automated UT with multi-channel probes scanned large castings on rollers.

• Result: Higher detection reliability of internal porosity.

• Lesson: Rough casting surfaces require surface preparation for accurate coupling.

Implementation Case – Pipeline Repair Weld Validation, Denver, Colorado

• Problem: Repair welds in pipelines required fast validation before pressurization.

• Solution: Mobile automated ultrasonic testing frames deployed for field weld inspection.
