Abstract
The invention relates to welding engineering. A welding head contains an external nozzle, two non-consumable electrodes connected with a drive of turning and isolated one from another, and also channel for guiding a consumable electrode. It is equipped with the drive of rotation of consumable electrode and with an internal funnel-shaped nozzle of heat-resistant dielectric material, the channel for guiding the consumable electrode is made in the form of openings in the nozzle walls.
