PAUT
Phased array ultrasonic testing for encoded weld inspection, flaw characterization, and complex geometries.
High-resolution ultrasonic inspection
Advanced Ultrasonic Testing Services
Advanced ultrasonic methods provide detailed, recordable inspection data for complex welds, corrosion, and material integrity assessments without damaging the component.
Inspection done right
Reliable results for critical assets
NVI combines phased array ultrasonic testing, full matrix capture and total focusing methods, time-of-flight diffraction, automated UT, and guided wave technologies to solve demanding inspection challenges.
Technique selection and scan plans are developed around the expected damage mechanism, component geometry, access, material, and acceptance criteria. Digital datasets support review, repeatability, trending, and informed repair decisions.
