ELECTRICAL RESISTANCE SEAM WELDING OF TIN BODY USING WIRE ELECTRODES |
摘要 |
<p>A method of manufacturing a welded can body from tinplate or a tin-iron alloy plated steel sheet comprises overlapping the opposite marginal portions of a blank of the tinplate or the tin-iron plated steel sheet to form a can body preform having an overlapping portion, applying at least to the cut edges of the marginal portions of the blank a fluxing agent promoting wetting of steel with molten tin, and electrical resistance seam welding the overlapping portion in a nonoxidizing atmosphere by employing a pair of wire electrodes each covered by a layer of metallic tin on the surface thereof facing the overlapping portion. The welded portion has improved corrosion resistance, as an extruded weld portion and a remaining cut edge surface portion thereof are covered with tin transferred from the surfaces of the wire electrodes and/or the tinplate during the welding operation.</p> |
