Abstract : The object of the invention is a method of automatic welding of immovable objects with a closed line of the seam, for example the nonrotary joints of tubes, with the aid of the electric arc burning between the parts of the object to be welded and shifted along the line of the seam. For the purpose of eliminating moving parts in the welding unit and assuring a uniform heating of the edges the shifting of the arc, including its anode and cathode spots, is accomplished by an immovable magnetic field produced in the zone of the shifting of the arc. The method may be modified by producing the welding arc between the objects to be welded and an auxiliary immovable nonfusible electrode which has the configuration of the outline (contour) to be welded. Nonfusible electrodes may be used one of which envelopes the object and the other placed inside.
