Abstract

An increase in the decay rate of a magnetizing field (to 0.01 s) favors the adequate detection of surface flaws in comparison with the slow (0.5–6 s) field decay (slow current cut-off). The circuitry of a power unit for a flaw detector, which allows the realization of the required rate of reduction, is suggested.
