Apparatus for overhead submerged arc welding

Apparatus for overhead submerged-arc welding

An apparatus for overhead submerged-arc welding has a rotatable hopper containing flux and accommodating a bowl communicating with a driven auger feeder having an auger rotating at a constant speed. In the bowl is extended a welding nozzle for a consumable electrode and a former is provided adjacent to the welding nozzle above the brim of the open part of the bowl facing towards a work being welded. The apparatus is also provided with a counter for counting the number of revolutions of the auger and a means for controlling flux supplied to the bowl which are connected to each other for actuating the latter when the auger has completed a preset number of revolutions. The means for controlling the amount of flux supplied to the bowl is made in the form of a shutter covering a port through which the hopper communicates with the driven auger feeder for varying the cross-sectional area of this port according to signals from the counter for counting the number of revolutions of the auger and an actuator mounted on the hopper and operatively connected with the shutter, the counter for counting the number of revolutions of the auger has an inductive pickup and a pulse count relay electrically coupled thereto.
