Abstract: The filler wire is a closed tube, in whose interior is located a filling of two or more pulverulent material components. With the split tube still open, the filling is introduced in the form of layers and then the split tube is closed. As a result of the filling introduced in layer form, a favorable set of conditions for closing or sealing the tube, for example by welding, is provided.

Abstract: Soldering wire constituted by a core of powder and a metallic tube enclosing the core of powder is produced by substantially filling an elongated upwardly open metal channel with the powder and introducing a profiled band into the thus filled channel which overlaps the powder at the open end of the channel and which engages the inner faces of the channel to keep the powder, during closing of the channel by bending upper longitudinally extending edges thereof into abutment with each other and subsequently welding these edges to each other, away from the longitudinal edges.

Abstract: A method for continuously producing a powder-filled tubular welding electrode, whereby a metallic band while being fed is formed to a gutter (16) and thereupon to a tube (21), whereby the edges of the gutter are welded together and welding powder is supplied via a conduit (18, 19) to the welded tube, and the welding powder free space of the tube being filled with a protective gas. The object of the invention is to provide a method for continuous production of a tubular welding electrode, especially a tubular welding electrode for welding without external supply of protective gas. The invention is characterized by the fact that the welding powder is introduced in a container (11), which is evacuated of an essential portion of its air content, whereupon the protective gas is introduced into the container until a positive pressure has been reached therein, and the powder-protective gas-mixture thereupon being supplied to the tube (21), whereby in the conduit (18, 19) is maintained a gas pressure, which is somewhat higher than the atmospheric pressure.

Abstract: A method for manufacturing powder-filled tubular welding electrodes made from a continuously fed metallic gutter (16) in which the powder is introduced through a powder conveyor (17) opening in the gutter, which conveyor via a filling conduit (19) arranged inside the gutter will transfer the powder past a welding station (23) for welding the longitudinal edges (25) of the gutter which is formed to a tube (21). The purpose of the invention is to provide a method and a device for manufacturing powder-filled tubular welding electrodes without the powder damaged when it passes the welding station and that the filling of a tube is made under controlled conditions thus that the tube is completely filled concurrently with its feeding through the welding station. This has been solved thereby that a pressurized gas is introduced in the filling conduit (19) for accelerated transport of the powder through the conduit, and that the pressurized gas is evacuated through an evacuation duct (31) provided in the tube (21) the inlet (30) of said duct governing the feeding of the powder, therein that the inlet at too big a powder volume is blocked by the powder, whereupon a counter pressure will be achieved in the filling conduit causing the powder feed to be reduced or completely prevented.

Abstract: A welding electrode of the filling type for machine or hand welding is formed by providing a longitudinally extending stepped ridge along one edge of a strip which is then bent transversely so that the opposite edge lies in the step and is a projecting portion of the step, underlies the gap, the resulting tubular member receiving the filling. The junction is then welded by tungsten inert gas or electron beam welding to close the shell and seal the latter.
