Eddy current testing (ECT)Profiled surfacesThe Eddy Current Testing (ECT) method forms part of the Electromagnetic Testing methods (ET) and is used to detect surface and subsurface discontinuities in conductive materials. Testing of conductive samples is also possible through limited thickness non-...
Eddy current is used to detect surface cracks, pits, subsurface cracks, corrosion on inner surfaces, and to determine alloy and heat-treat condition. A wide variety of eddy current test instruments are available. The eddy current test instrument performs three basic functions: generating, receiving,...
It can detect surface-breaking, near-surface, and far-surface defects. ECT probes don’t need to be in contact with the part under inspection. Eddy current testing can be used in applications other than flaw detection. Parts under test require only minimal preparation. ...

Quality control of Rutherford-type cables by the eddy-current test method An eddy-current testing technique is reported that was used to detect defects in the flat Rutherford-type cable of the HERA (Hadron Electron Ring Accelerat... D Salathe,RK Maix - 《IEEE Transactions on Magnetics》 被引...
3.4.4.6Eddy-current testing Eddy-current testingis the less successful technique for the inspection of composites, and requires electromagnetic induction of electrical current on the component surface. This is generally used to detect the aerospace surface crack inspection. Prakash and Owston used this ...

Meanwhile, Eddy current inspection technology is applied to detect the surface crack or subsurface crack with orthogonal difference array probes, which helps ... Z Lifeng,C Zhaoyu,C Jiafan,... 被引量: 0发表: 2017年 Eddy current effects in a high field dipole Eddy currents produced by a ti...
Eddy current testing uses electromagnetic induction to detect defects in both ferrous and non-ferrous materials by inducing an eddy current field in the specimen under test. A variety of inspections can be performed with eddy current testing and it is typically used for surface and near-surface fl...
The SV-GMR sensor serves as a magnetic sensor for the ECT probe to sense the variation of the magnetic field distribution occurred on the printed circuit board. The SV-GMR sensor is used specifically to detect the changing magnetic field distribution occurred at the defect point. The ...
