Abstract:
PCT No. PCT/SU88/00259 Sec. 371 Date Feb. 6, 1990 Sec. 102(e) Date Feb. 6, 1990 PCT Filed Dec. 14, 1988 PCT Pub. No. WO89/11942 PCT Pub. Date Dec. 14, 1989.An apparatus for overhead submerged-arc welding a hopper containing flux and accommodating a bowl having means for supplying flux and its pressing and having its open upper part facing towards a work being welded, a rear wall of the bowl in the welding direction being made in the form of a movable plate supported by a pivot pin extending perpendicularly with respect to its surface. Adjacent to a movable plate in the bowl is mounted a welding nozzle for supplying a consumable electrode and a forming means is provided above the brim of the open part of the bowl on a suspension supported by a pivot pin for cooperation with the movable plate and for oscillations in the longitudinal and transverse planes, and the hopper is suspended on the pivot pin of the suspension of the forming means. The pivot pin supporting the movable plate is mounted on a means for pressing an upper end face of the movable plate against the front end extremity of the underside of the forming means. Such construction of the apparatus during welding prevents accumulation and jamming of the flux in the bowl under the forming means, creates the optimum conditions for oscillations of the forming means and provides for automatic maintenance of preset pressures of the flux on different parts along a joint being welded. The invention may be preferably used for welding longitudinal and rotatable annular joints.
