PURPOSE:To provide a joining method for fine wire which can obtain no defect welded joint and is simple in work with reduced manhours. CONSTITUTION:By butting the end faces of wires 2, 3 to be joined, irradiating the butt part with laser beam, melting the ends of each wire and feeding one of wires at least in the direction toward a melted part, the molten lump 8 having the outer diameter larger than the outer diameter of each wire, subsequently, by pulling back one of wires in the opposite direction toward the molten part, a shape of the molten part 9 is adjusted and joined. |
