Abstract
A method is disclosed for checking and obtaining in a moving mode the continuity of a metal covering on a metal wire of different nature belonging to the group of a wire being treated by a current strength and issuing from a covering bath and wire, the treatment of which is achieved and coming from a storage wheel. The method comprises continuously bringing the coated wire in contact with a volume of electrolyte solution chemically and physically inert with respect to the wire, and in which the sensitive part of a reference electrode is immersed, sliding the wire issuing from the volume against an electrical contact, measuring the electrical potential variations between the electrode and the contact, and when the potential current oscillates, noting the poorly covered wire and increasing the current strength on the wire being treated.
