What Is Eddy Current?
In eddy current testing electrical currents are generated in
a conductive material by an induced magnetic field. Distortions
in the flow of the electric current (eddy currents) caused
by imperfections or changes in a material’s conductive
properties will cause changes in the induced magnetic field.
These changes, when detected, indicate the presence of the
imperfection or change in the test material.
Typical Applications
Thickness Determination of Materials
Conductivity Sorting of Materials
Inspection of Welds
Inspection of Aerospace Materials
