IPC: G01N27/90
Filed: 1990-09-13
Abstract: PURPOSE:To enhance the inspection accuracy of flaw detection by applying drawing processing to a material to be inspected immediately before flaw detection. CONSTITUTION:The copper wire 10 pulled out of a drum 12 by the rotation of a take-up bobbin 14 is quided to a drawing die 20 by a guide roller 22.

Immediately thereafter, the surface of the copper wire 10 is subjected to flaw detection by a probe coil 16 and an eddy current flaw detector 18. Since the copper wire is almost round, a change is generated in the current value inputted to the eddy current flaw detector 18 only when the surface of the copper wire 10 has a flaw and the erroneous detection due to the deformation of the copper wire 10 itself is prevented. Therefore, even a small flaw of about 0.05 mm depth can be detected.
