Abstract

1351691 Electrometallizing spray gun KOVFINIS NARODNI PODNIK 3 Sept 1971 [4 Sept 1970] 41292/71 Heading B2F An electrometallizing gun has a nozzle with a through hole for a propellant gas stream, two passages communicating with the through hole, each containing a wire to be melted, and two guides outside of the through hole through which the wires are faced in the direction of the passages, the passages being so designed that the wires enter at least partly into the through hole close to its orifice. In the figure, wires 10 are guided through guides 16, which are narrower at the outlet near the orifice than at the inlet, and emerge on paths which intersect in front of the hole 12 near the front head part of the nozzle. The wires partly enter the through hole 12 near the outlet orifice. The wires are supplied with electric voltage at a point not shown and an electric arc thus burns between their ends and melts the metal, which is then sprayed by the stream of propellant gas (air). The air may be supplied as in the figure by a venturi 26.
