Abstract
Features of TIG-welding of aluminium alloys by arcs facing each other were studied. Compared to the regular processes which envisage weld formation from one side, an essential increase of metal penetration has been achieved with the weld width comparable with the base metal thickness and a favourable appearance of the weld from both sides of the joint.
Keywords: arc welding, nonconsumable electrode, aluminium alloys, opposite arcs, penetrability
