PROBLEM TO BE SOLVED: To provide an arc welding method and its device for performing easy, sure, and proper welding while controlling a shape of a molten metal corresponding to conditions such as an arrangement of a welding object. SOLUTION: A welding object 1 is fused and jointed by arc discharge. A magnetic field H is generated at a molten metal portion where the welding object 1 is melted, and an electromagnetic force F generated by an electric interaction of the magnetic field H and an arc current I is added to a molten metal 2, so as to perform welding while controlling a shape of the molten metal 2. |
