Abstract

The problem of inspecting tubes and tubular articles from the inside in a nonuniform field of a through-type eddy-current transducer is considered. Based on an analysis of the transducer’s signal, sensitivities to the inspected tube’s wall thickness and to changes in the electric conductivity are calculated. The inspection is optimized and the appropriate plots are presented.
