Eddy Current Testing Equipment
Eddy current testing (ET) is a non-destructive electromagnetic method for detecting surface and near-surface defects in electrically conductive materials. NDT1 Kraft supplies the ED eddy current equipment for flaw detection and material inspection.
Eddy current flaw detection
An alternating current in the probe coil induces eddy currents in the test part; cracks, corrosion, porosity and changes in conductivity disturb those currents and are registered by the instrument. Because eddy current testing needs no couplant and works through thin non-conductive coatings, it is fast and well suited to in-service inspection.
Typical applications include crack detection in welds and machined components, inspection of tubes and pipe threads, and conductivity or heat-treatment checks on aluminium and other non-ferrous alloys in the aerospace and automotive industries.
FAQ
What materials can be tested with eddy current?
Electrically conductive materials — steels and non-ferrous metals such as aluminium, copper and their alloys.
What defects does it find?
Surface and near-surface cracks, corrosion, porosity and conductivity variations.
Does it work through coatings?
Yes, eddy current testing works through thin non-conductive coatings without removing the paint.
