Abstract

PURPOSE: This device delays an eddy flaw detecting signal when the eddy flaw detecting signal is induced in an ultrasonic wave flaw detecting line, and sorts the quality for the steel materials on the basis of the ultrasonic wave flaw detecting signal and the eddy flaw detecting signal through the signal treatment part.
