The invention discloses an arc-welding workstation. The arc-welding workstation comprises a workbench; a rotatable slewing device is arranged on the workbench; two symmetrically-arranged clamping devices capable of being overturned up and down are arranged at two ends of the slewing device; arc-welding robots are arranged in the positions, located between the two clamping devices, of the slewing device; a repair-welding robot adapted to the slewing device is arranged at one end of the workbench; an automatic protecting door is arranged at the other end of the workbench; and the arc-welding workstation further comprises a welding wire supplying device for supplying welding wires. According to the arc-welding workstation, the arc-welding robots are arranged in the center of the workstation,the spare space of a rotary table is sufficiently utilized, a loading robot, an unloading robot and the repair-welding robot are arranged on the periphery of the workstation, switching welding is performed at two welding stations, flexible switching is realized, the stand-by time of the welding robots is shortened, workpieces can be welded continuously by the arc-welding robots, the utilization ratio of the arc-welding robots is increased, and the welding efficiency is substantially improved.
