Abstract:
    Methods and apparatus for performing an inspection using an eddy current coil are described. In one embodiment, the method is for inspecting an embossment of a wheel for a gas turbine using an inspection assembly (10). The inspection assembly includes a fixture and an eddy current coil. The fixture includes a stability support (22) and support bearings (56). The method includes positioning the assembly so that the eddy current coil is over the surface to be inspected and so that the support bearings are on the surface, and maintaining the stability support against a support surface.
