Large-sized robot welding workstation with flue dust treatment function

The invention discloses a large-sized robot welding workstation with a flue dust treatment function. The large-sized robot welding workstation comprises a safe enclosure of a welding workshop, a welding location control system, a workpiece turnover platform, a flue dust treatment robot welding system and a workstation controller, wherein the workpiece turnover platform and the flue dust treatmentrobot welding system are arranged in the safe enclosure of the welding workshop; the welding location control system is arranged above the flue dust treatment robot welding system; and the welding location control system, the workpiece turnover platform, the flue dust treatment robot welding system and the workstation controller are electrically connected. With the welding location control systemand the workpiece turnover platform, the welding range and the degree of freedom are extended, and the problem of small welding operation range of the welding robot is effectively solved; a high-pressure contact sensor is adop
