Abstract
A flaw detection device, and method of operation thereof, for inspecting an entire workpiece, such as a tube or pipe, for the presence of defects. The detection device includes a plurality of pickup arms mounted in spaced relation with respect to each other around a work path, and a plurality of sensing coils carried by each of the pickup arms. The pickup arms are each mounted on a support member to pivot on an axis transverse to the direction of the work path so that the sensing coils may be moved into proximity and around the circumference of a workpiece as the workpiece travels along the work path.
