Abstract
A method for inspecting a metallic component comprises providing an inspection standard having an eddy current signature substantially similar to an eddy current signature of the metallic component, wherein the inspection standard body is fabricated from a non-metallic material. The method also comprises inspecting the metallic component with an eddy current probe with reference to the inspection standard.
Claims20
A method for inspecting a metallic component, said method comprising:
- providing an inspection standard fabricated from a non-metalic material and having an eddy current signature substantially similar to an eddy current signature of the metallic component being inspected;
- and
- inspecting the metallic component with an eddy current probe with reference to the inspection standard.
An inspection standard comprising:
- a body fabricated from a non-metallic material and comprising an outer a plurality of grooves extending across said outer surface;
- and
- at least one conductor positioned within at least one of said grooves.
An inspection device comprising:
- an inspection standard comprising a non-metallic body;
- and
- an inspection device comprising a probe in close proximity to said inspection standard.
