Abstract

Mechanised welding appts. for gas-shielded or powder cover welding or the base layer as well as the filling and covering layers of metallic materials, comprises (a) a welding current source; (b) a wire-feed system for synchronised supply of two weld wires electrically insulated from one another; and (c) a gas-shielded or powder-covered welding torch, in which the two mutually electrically insulated wires are transported to the weld position. On displacement of the double wire torch from the centre of the weld seam, resistance or current differences resulting in the two current branches are measured, the difference signal being supplied to a known amplifier and control unit in order to continuously return the torch to the centre of the weld seams by means of a displacement-producing motor. Enables satisfactory welded joint to be made from one side only with automatic maintenance of the weld torch centrally over a straight or curved weld seam.
