Investigation of Eddy Current Techniques for the Inspection of Gun Tube Bore Evacuator Holes.

Abstract

A commercially built multiple-frequency eddy current system, with several commercially available bolt-hole probes, was used to detect EDM slots in a section of 120-mm gun tube in which holes were drilled to simulate bore evacuator holes. The experiments performed demonstrated the possibility of slot or crack detection with these defects originating at the hole-surface interface. However, defect characterization and inspection by this method does not appear feasible. (Author)
