A method of continuously manufacturing a welding electrode comprises coating a metal core member 1 with a filler material in the form of a layer of coherent paste 4 under substantial pressure, passing the coated core through a drying kiln 7 and then bringing an outer metal strip 11 into contact with the coated core member and deforming it around the coated core to form a tubular sheath, and finally closing the joint in the sheath by a continuous welding operation. |
