FIELD: metallurgy.
SUBSTANCE: electrode feeding mechanism, fixed guides for electrodes and a flux feeding system are mounted on a welding head body. Adjustable levers with current-carrying jaws are hinged on additional electrode guides. A splitter connected in the lower part to a contact insert is located between fixed guides. The contact insert is replaceable and has thickness of 4 to 30 mm and equipped with cooling channels. In each current-carrying jaw there are 2 longitudinal slots 2.5-5 mm wide and 1.5-3 mm deep with distance between them of 4.5 to 5 mm.
EFFECT: welding head allows improving quality of weld metal and is reliable when performing large scopes of surfacing or welding operations.
