摘要： In order to enable highly efficient welding without the generation of weld defect such as undercut, overlap, and defective meeting angle, a plurality of additive wires (5a, 5b) are inserted into a melting pool (12) during horizontal welding, a unidirectional current is made to flow between the wires, and a magnetic field (9) is used to provide a magnetic field to the melting pool substantially in a direction perpendicular to a surface of a parent metal so as to cause the melting pool (12) to generate upward (antigravitational direction) Lorentz's force (11), whereby a molten metal is lifted upward to prevent dripping of the molten metal and to improve its bead shape.
