ELECTRODE OF MACHINE FOR CONTACT WELDING OF STRIPS BY MELTING Russian patent published in 2010 - IPC B23K11/30 B23K11/04 

FIELD: welding works.

SUBSTANCE: invention may be used in contact butt welding of strips in continuous metallurgical units, for instance in etching lines or units of longitudinal cutting, which mostly process strips of high-carbon steels. Grip joined to feed bar is equipped with conductor insert arranged as front relative to axis of welding and back pressing plank. Conductor insert is arranged with semicircular groove, which is parallel to side end of insert. Conductor element is installed in groove and interacts with it. Its flat surface is arranged as protruding over insert surface by value of at least 0.3 mm. Distance from side end of insert to beginning of semicircular groove makes 2…4 mm. Conductor element is produced by installation of annealed copper wire bar in semicircular groove and its further deformation for arrangement of flat surface.

EFFECT: improved quality of welded butt by provision of even heating of welded joint along its length with simplification of machine design for contact welding.
