We carry out Eddy Current Testing on welds and wrought products using qualified personnel.
Eddy current testing is a non-contact electromagnetic testing technique used for the inspection of conductive materials without the need to remove non-conductive coatings. An alternating current is passed through a coil in order to create an alternating magnetic field which is used to induce a localised current (eddy current) into the material under test. Eddy current is routinely used to inspect a wide range of different materials and components across several fields of engineering including oil and gas, nuclear, power generation and aerospace.
Some advantages of eddy current inspection include:
Sensitive to small cracks and other defects
Detects surface and near surface defects
Inspection gives immediate results
Equipment is very portable
Method can be used for much more than flaw detection
Minimum part preparation is required (sensitive to ‘lift-off’ from spatter, etc.)
Test probe does not need to contact the part
Inspects complex shapes and sizes of conductive materials
Test through paint/non-conductive coatings up to 2mm thick
In the proper circumstances, eddy currents can be used for:
Material thickness measurements (On thin material)
