  • Patent number: 12498355
    Abstract: A system and method of ultrasonically inspecting coiled wire includes a wire drawer, a first power feeder, an ultrasonic inspection device, and a re-coiler. The wire drawer receives wire that is unspooled from a first coil of wire that has not been internally inspected for defects. The wire is then fed through the first power feeder, which straightens the wire. The straightened wire is then fed through the ultrasonic inspection device to detect internal defects of the wire. The inspected wire is then re-coiled into a second coil of wire that has been ultrasonically inspected for internal defects. Accordingly, raw and uninspected wire coils can be continuously conditioned and inspected and then re-coiled, and may be certified for use in specific manufacturing processes, without having to inspect individual cut and separated sections of wire.
