Abstract
A method is disclosed in which gas shield arc welding is carried out while applying a gas at a higher pressure than the shield gas to the rear part of the surface of molten metal during welding. By this method, welding proceeds while the molten pool is being maintained in the desirable shape, and the welding can be performed at high currents and speeds without causing bead defects such as undercut formation or humping.
