How Ultrasonic Non Destructive Testing Keeps Ships Safe Beneath the Surface

Ultrasonic non destructive testing works by transmitting high-frequency sound waves through metal and analyzing the returning signals. When those waves encounter internal corrosion, cracks, or voids, the reflection pattern shifts. A skilled technician reads those shifts to build an accurate picture of what’s happening inside the steel, without cutting into it, without drydocking, and without disrupting a vessel’s operational schedule.
