TWI is a globally recognised resource for engineering design, structural health monitoring and non-destructive testing (NDT).
As a result, we have expertise in a wide range of different techniques that are used for quality and inspection in metals processing and manufacturing, including in the aluminium industry.
Here we discuss the principles and practice of eddy current testing, which is used for flaw detection, material and coating thickness measurements, material identification and establishing the heat treatment condition of certain materials:
