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.
