FIELD: electricity.
SUBSTANCE: at the same time, two laser beams are used for welding. The laser beams are located on the side of the outer surface of the edge butt of the pipe billet. The filler wire, melted with electric arc, is fed into the welding zone in a protective gas with the formation of a single weld pool. The electric arc is placed behind the beams to fill the groove of the pipe billet. The axes of the beams are placed in one plane perpendicular to the welding direction and at equal angles from the vertical axis, intersecting them in the focus region. The focus is located above the surface of the workpiece and the regions of defocusing are located to let the beam hit the opposite edge of the butt.
EFFECT: improving the quality of the welded joint when welding the edge butt of the billet with both the maximum permissible gap and excessive gap.
