Cables, wires, wire-strands and rods all have one thing in common – transmission. It can be the transmission of power such as for electricity, of mechanical movement such as in pulley systems, or data such as in telecoms, etc.
Modern continuous in-line production does not allow for spot tests to give overall reliable assurance on quality. This kind of situation requires an in-line detection system to detect flaws preferably before they enter the production line – and flaws can occur, as the source material can introduce inclusions and ingot segregations, there can be production dependent weld joints, cracks, dents and mechanical joints, etc. The purpose of such a system should be to detect such defects before they end up in the final product.
Relying on its key competencies in Eddy Current technology, one of Evanet’s partners developed a system, the UFD40 series, to satisfy the above needs. Being in-line and suitable for all metals, it can accept wire diameters from 0,5 to 90 mm, including the cable jacket, and operate at production speeds of 0,6 to 600 m/min.
A selection of detectable faults include weld seams in copper rings (for positioning purposes), weld seams inside coated flexible shafts and Bowden cables (the welded seams have to be removed before further processing), junctions in heating cables so that they can be marked for proper mounting, weaving defects in shielding and ground cables which need to be removed during rewinding, butt weld joints in copper cords (no steel markers required for detection), hidden mechanical joints in cables, defects in twisted wire pairs and scratches and cracks in thin wires.
