<p>MACHINE FOR PRESSURE CONTACT SEAM WELDING Disclosure is made of a machine for pressure contact seam welding, comprising a table carrying a work-piece and electrodes positioned opposite each other and electrically connected to each other. At least one electrodes is mounted so that it can be brought closer to the other electrode in order to produce an ela stic static force in the welding zone. The machine comprises a slideway to forcibly keep the welded material in the zone of contact with the workpiece and the electrodes, a real of the welded material, a pitch feed mechanism to deliver the welded material from the real to the zone where it is gripped together with the workpiece by the electrodes, and a device for separation of the required length of the welded material. This device for separation of a required length of the welded material comprises, according to the invention, a mechanism for stopping the delivery of the welded material after it is welded to the workpiece, which is controlled by a welding end pickup and, as a result, the welded material is torn away in the zone of contact of this material with the workpiece and the electrodes.</p> |
