A method for inspecting a component having a surface profile that includes a local minima and a local maxima. The method includes positioning an eddy current probe proximate to a surface of the component to generate a first position indication, positioning the eddy current probe proximate to the surface of the component to generate a second position indication that is different than the first position indication, and interpolating between the first and second position indications to determine a profile of a portion of the surface of the component.

Methods and apparatus for testing a component

A method for inspecting a component. The method includes generating a scan plan of a component to be inspected, coupling a side-mount probe to an eddy current inspection system, inducing an eddy current into the component, measuring the eddy current in the component to generate a plurality of scan data, and analyzing the scan data to generate at least one image of the component being inspected.

The present invention provides an eddy current array probe having a complaint body molded around a rigid insert. A flexible eddy current array circuit is wrapped around the outer surface of the compliant body.

Molded eddy current array probe

A calibration standard for calibrating an eddy current inspection probe sized and shaped to inspect a preselected non-planar feature of a manufactured part. The feature extends in a longitudinal direction and in a lateral direction. Further, the feature has an end profile as viewed in the longitudinal direction having a substantially invariant shape and orientation. The calibration standard includes a body having a non-planar surface extending in a longitudinal direction and in a lateral direction. The standard also has an end profile as viewed in the longitudinal direction of the surface substantially identical to the profile of the feature. The surface of the body has an elongate narrow opening extending into the body substantially normal to the surface and traversing the surface of the body at a substantially constant angle with respect to the longitudinal direction of the surface as viewed normal to the surface.
