Abstract

An electrothermal method of nondestructive inspection of conducting materials is proposed and tested experimentally. This method is based on filming the IR emission of the surface induced in a sheet sample excited by a millisecond current pulse. Subsequent computer processing of the nonstationary thermalfield patterns reveals millimeter and submillimeter defects and provides an opportunity to estimate their geometrical parameters and the temperature-diffusivity coefficient of the material.
