摘要： A method for producing a molten puddle on the surface of a metal workpiece to be scarfed consists of igniting a mixture of fuel gas and oxygen. The resultant flame is used for heating a steel wire to a temperature of from 900.degree. to 1450.degree. C., whereupon the steel wire is intermittently fed into a stream of scarfing oxygen to produce droplets of molten metal, which are then transferred by a flow of scarfing oxygen on to the work surface. There is provided apparatus for carrying into effect the above method, which comprises a housing having ducts for supplying a fuel gas and oxygen formed on its periphery; an additional duct for supplying a fuel gas being made in the central part of the housing; a duct for feeding steel wire is provided in the housing in coaxial arrangement with the additional fuel gas supply duct; a scarfing oxygen feeding duct formed in the housing is interposed between the oxygen supply duct and the additional fuel gas supply duct. The duct for feeding a scarfing oxygen is made in the form of a tapered annular slot arranged to permit the stream of scarfing oxygen to be directed at one point on the surface of steel wire.

摘要： A method for powder scarfing of metal resides in that combustible gas and oxygen are fed to a zone (9) of treating a metal (10) in order to form a heating flame. Then, flux is delivered by means of a flux-carrier gas, whereupon the former is separated from the latter, and the separated gas is discharged. The flux is directed to the zone (9) of treating the metal (10) in-between the jets of combustible gas and oxygen, whereupon the flux is melted in a heating flame to form a molten bath in the metal treating zone (9). An apparatus for carrying into effect the above method comprises a body (1) formed with ducts (2), (7), (13) and (16) for supplying combustible gas, oxygen and flux therethrough, which open into an outlet cavity (8) presented to the metal treating zone (9). Mounted on the body (1) is a separating chamber (18) having a gas outlet (23) and a pipeline (21) for supplying flux into the separating chamber (18) by means of a flux-carrier gas. The separating chamber (18) has its bottom part, adjoining the body (1), formed with a flux outlet opening (25), and the wall of the body (1) adjoining the separating chamber (18), has a tapered projection (26) spaced opposite the flux outlet opening (25). Formed by the tapered projection (26) and the walls of the body (1) is an annular cavity (27) which is brought in communication with the outlet cavity (8) through ducts (32), intended for supplying flux to the zone (9) of treating the metal (10).
