Automatic gas shielded welding machine

The invention discloses an automatic gas shielded welding machine which comprises a machine tool, a vibration screening disc and a welding frame are arranged on the machine tool, a workpiece clamp, a carbon dioxide wire feeding welding head and a pushing mechanism are arranged on the welding frame, a discharging sliding way is arranged on the vibration screening disc, and the discharging sliding way is in butt joint with the workpiece clamp. Workpieces to be welded enter the workpiece clamp along the discharging sliding way in a queuing mode, the carbon dioxide wire feeding welding head is located on one side of the workpiece clamp, when the carbon dioxide wire feeding welding head gets close to and makes contact with the workpieces, welding is completed, and the pushing mechanism acts on the workpiece clamp to push out the welded workpieces for discharging. According to the automatic gas shielded welding machine, a series of actions of automatic feeding, welding and discharging of parts are achieved, a proper workpiece clamp is selected for specific part shapes, the equipment structure is simple, the cost is low, the welding quality is good, and the machining efficiency is improved.
