Eddy Current Testing (ET) is one of the non-destructive testing methods which is used to inspect surface and near-surface discontinuities in conductive materials. This testing method is widely used in industries such as aerospace, manufacturing, oil & gas and more. Eddy Current testing has many benefits such as
Ability to detect very small discontinuities on surface and near-surface
No need to remove coatings
Able to inspect parts with complex geometries
Can cover a large area of inspection in one scan
No need to clean the parts after inspection
Eddy current testing (ET) can be used to inspect both ferromagnetic and non-ferromagnetic materials. There are many types of defects that ET can used to find the defects including:
Crack
Corrosion
Wear
Lack of fusion
Pitting
Wall loss
