ABSTRACT:
The invention concerns arc welding in a narrow gap. According to the invention, the tip (6) of the electrode wire cooperates with the wire guide tube to oscillate in a plane (P) perpendicular to the line of advance (D) and to either side of a median line (Ye) inclined at an angle (I) with respect to the centeline (Yg) of the wire guide tube, this oscillation being bounded alternately by the edge of one of the pieces and by the previous bead. The invention applies to arc welding with a consumable electrode under a protective atmosphere and in a narrow gap, in flat, vertical and overhead weld positions.
