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.
