Abstract

PURPOSE: To hold molten pool through pressing of the electromagnetic force being generated, make welding of various postures eacy and improve quality by feeding consumable electrode through the magnetism generating coil supplied with alternating currents.
CONSTITUTION: A magnetism generating coil 1 provided with the through-hole 1a at the position opposing to the material 2 to be welded is so disposed as to approach to molten pool. Next, the olternating currents of frequency above 100Hz per lμΩ.cm in specific resistance of the material to be welded are supplied to the magnetism generating coil. A welding electrode 6 is supplied through the through-hole 1a from a contact tube 7 from the shortest distance in the direction nearly orthogonal to the material 2 to be welded, whereby welding is accomplished.
