ABSTRACT:
A rotary arc-welding apparatus which comprises: a rotatable nozzle having in its interior thereof a passage for directing a consumable welding electrode eccentrically from the center axis of the nozzle toward a groove formed between objects of welding; a consumable welding electrode feeding mechanism for continuously directing the consumable welding electrode toward the groove through the nozzle; a welding current feeding mechanism for feeding a welding current to the nozzle, which comprises a current receiving plate fixed to the top end of the nozzle, a brush having on the upper surface thereof a current feeding plate, the brush and the current receiving plate having a flat contact interface therebetween, a plurality of rods for stationarily holding the brush and the current feeding plate, and a plurality of springs for applying a pressure onto the contact interface between the brush and the current receiving plate; a nozzle rotating mechanism for rotating the nozzle about the center axis thereof at a high speed to cause a circular movement of an arc from the tip of the consumable welding electrode corresponding to the eccentricity thereof; and a shielding gas feeding mechanism for feeding a shielding gas toward the arc and a weld zone.
