Zusammenfassung:	PCT No. PCT/SU88/00264 Sec. 371 Date Feb. 27, 1990 Sec. 102(e) Date Feb. 27, 1990 PCT Filed Dec. 14, 1988 PCT Pub. No. WO89/11946 PCT Pub. Date Dec. 14, 1989.An apparatus for overhead submerged arc welding has a hopper containing flux being pivotally mounted on a suspension for rotation about the suspension axis, the hopper having a bowl provided in the top part thereof, a welding head with a nozzle for supplying a consumable electrode, and means for supplying flux and pressing it against work. The apparatus also has a forming means mounted for swinging in its longitudinal and transverse planes and for a vertical adjustment with respect to the work being welded. The forming means is in the form of a U-shaped body having its open top part facing towards the work being welded and legs having on the side of the nozzle a pair of diverging wedge-shaped projections, an adjusting bar being provided inside the body to extend length-wise of the joint being welded. Copying members in the form of four wheels are provided outside the body on either side of the legs thereof. This construction of the forming means ensures maintenance of preset flux pressures at various points along the joint being welded.
