Abstract

Surface defect detecting apparatus comprises at least one non- contacting eddy current flaw detecting sensor (3) mounted on a cylindrical member (2) rotatable at constant speed. Cylindrical metallic material (1) is fed at constant speed axially into the member (2), whereby its outer surface is spirally scanned for surface defects by the sensor (3). The length of feed of workpiece (1) and the angle of rotation of the cylindrical member (2) are measured by detectors (15, 13). The size and location of a flaw is registered by an output dependent on the signals from the sensors (3), length measuring means (15) and turning angle detector (13). The cylindrical member (2) is autocratically adjusted vertically and horizontally to reduce any eccentricity relative to the workpiece in response to signals from a distance sensor (11 Fig. 3) for measuring the gap between the sensors (3) and the workpiece (1), and from the turning angle detector (13). An automatic gain control circuit responsive to signals from the distance sensor (11) controls the detection signal level from sensor (10) Fig. 1 in accordance with changes in the gap. <IMAGE>
