1. EDDY CURRENT
TESTING

2. EDDY CURRENT TESTING (ECT) IS THE PROCESS
OF RUNNING ELECTRONIC PROBES THROUGH
THE LENGTH OF VARIOUS TYPES OF TUBES OR
ALONG THE SURFACES OF MATERIALS IN ORDER
TO FIND FLAWS IN THEM.

3. IT IS ONE OF THE MOST SEVERAL
ELECTROMAGNETIC TESTING METHODS
USED FOR NON-DESTRUCTIVE TESTING
(NDT), WHICH REFERS TO TESTS
PERFORMED FOR THE PURPOSE OF
INSPECTIONS THAT DO NOT DAMAGE THE
MATERIAL BEING TESTED.

4. EDDY CURRENT TESTING CAN SUCCESSFULLY TEST
ANY CONDUCTIVE, NON-MAGNETIC, OR MILDLY
FERROMAGNETIC MATERIALS.

5. PICTURES NG MATERIAL NA CONDUCTIVE, NON-MAGNETIC
AT MILDLY FERROMAGNETIC MATERIALS.

6. THE TYPES OF FLAWS EDDY CURRENT TESTING USED TO
FIND:
 FREEZING-RELATED DAMAGE (in tube)
 CRACKS
 CORROSION
 WEAR (in tubes, often due to erosion)
 PITTING
 WALL LOSS/THICKNESS LOSS
