An eddy current inspection device is made smaller without reducing the detection capability of the device. SOLUTION The eddy current inspection device 10 applies a magnetic field to the inspection object 1, generates an eddy current in the inspection object 1 by an electromagnetic induction phenomenon...
An eddy-current inspection method comprises: synchronization steps (S3, S4) of synchronizing the phase of exciting voltage with the phase of driving voltage, the exciting voltage being applied by a coil driving means to an exciting coil for generating eddy current in a body to be inspected, the...
3.4.4 Eddy current inspection Eddy current testing is considered to be one of the most trustworthy techniques for monitoring aerospace composites [78]. This method of inspection works on the principle of the interrelationship between the material under testing and the type of origin of the magnetic...
Eddy current inspection Abstract The eddy current non-destructive inspection technique can be used effectively on fibre metal laminates. It uses the principle of electromagnetic induction, i.e. the interaction between a magnetic field with an electrically conductive object. With this method, the ...
Eddy Current Testing Abstract The application of non-destructive test methods in quality control of semi-finished and finished products is of maximum economic importance in modern industry. The development of the eddy-current method of inspection has involved the use of several scientific and ...
