Abstract
PURPOSE:To achieve the stabilization of the arc and make possible the controlling of globule migration mode, deposition amount, etc. by providing a consumable electrode for MIG welding and plural consumable electrodes for TIG welding respectively to the central part and its circumference and encircling the wire tip and arc of the former by the arc of the latter. CONSTITUTION:For example, consumable electrodes 3, 6 and 7 for MIG and TIG welding are disposed as shown in the figure, and with these as anode, and the welding work 1 as cathode or by making these to the opposite polarities, the welding is performed. This causes the arc A generated by the central electrode 3 to be effectively converged by the arcs B, C having the directivity in the central direction generated by the surrounding electrodes 6, 7, thereby enabling powerful arc throttling power, that is, pinch force, to be obtained. This pinch force and the wire tip are effectively preheated by the surrounding arc and are thereby pointed at the end, by which the stable spray arc may be maintained and globule migration mode is improved. Further, the amount and shape of penetration may be controlled by dispersing the welding current to the electrodes 3 and 6, 7.
