Abstract
An automatic weld flaw detector comprises a comparator for comparing the height of an echo from a detected flaw upon movement of a probe over each unit distance with a maximum echo height already known, a counting circuit adapted to work in response to the comparing action of the comparator so as to determine the distance the probe has covered, a device adapted to be actuated by the output from the comparator thereby to memorize separately the maximum value of echo height and the output at that moment from the counting circuit, and a recorder connected to the memorizing device.
