Abstract
Method and apparatus for non-destructively testing fabricated metal components with eddy currents. The apparatus includes a coil for generating a magnetic field and means for concentrating the magnetic field into a small inspection volume in the component being tested. The magnetic field induces eddy currents in the component. The coil and the field concentrating means are moved in a manner to scan the component in a predetermined manner with the concentrated eddy currents.
