Electrode Potential Method of Bond Testing


The electrode potential method of bond testing utilizes the principle that the electrical resistivity in the immediate neighborhood of a flaw differs from that in solid metal. In this method, potential difference is used as a flaw indicator. Specially designed electrodes have reduced the disturbing effect of surface contact resistance common to resistance methods to a negligible factor and have made continuous semiautomatic scanning of a specimen possible. A pilot bond tester utilizing this method has been constructed and is described.
