ABSTRACT:
Aluminum and aluminum alloys are welded in a horizontal welding position in which the base metals to be welded are vertically disposed in abutting relationship with the welding groove opened sidewise by oscillating the tip of the welding electrode in the widthwise direction of the abutted base metals and welding the base metals while maintaining the angle formed by the surface of the molten pool and the electrode on the advancing side thereof greater than 90.degree.. The surface of the molten pool as used herein is defined as one which is parallel to the crater surface of the weld which results upon termination of welding by extinction of the welding arc.
