摘要： PROBLEM TO BE SOLVED: To provide a welding method enabling high efficient welding without generating defective welding or the like and welding equipment suitable for realizing the welding method. SOLUTION: This welding equipment is roughly composed of an arc generating means consisting of a welding torch 1, a welding wire 2 and a welding power source 7 which generate an arc 3 facing a stock 6 to be welded and which form a molten pool 4 and a magnetic field generating means 10. The magnetic field generating means 10 is composed of a coil member and an iron core 10b having a shape divided into two segments in the longitudinal direction of a pipe shaped columnar body. That is, the iron core 10b is asymmetrically arranged to a flat surface including a coil member axial line. According to this welding method, 'a magnetic field' the intensity of which is spatially deviated is imparted to the arc 3 or the molten pool 4 with the asymmetrical iron core 10b, Lorentz's force is exerted on the arc 3 or the molten pool 4, and whereby welding progresses so that the dropping of a molten metal from a groove 60 or the like is not generated.
