Eddy current testers are based on the detection of variations in the electrical conductivity and magnetic permeability of a metal surface. It is commonly used in manufacturing to inspect thin metal ...

There are six common NDT methods: visual testing, liquid penetrant testing, magnetic particle testing, eddy current testing, radiographic testing, and ultrasonic testing. Each method requires a ...

Aside from industrial radiography, four of the most common methods are: ultrasonic radiography; and liquid penetrant, magnetic particle and eddy current inspections. Non-destructive testing is a key ...
