[0038] Therefore, 1. The workpiece to be welded is placed between the lifting mechanism 3 and the welding platform 2 so that the workpiece can be stably clamped under the action of the lifting mechanism 3. Then, the welding machine can enter the welding hole 21 through the insertion hole 23 and the collecting chamber 22, and weld the part of the workpiece to be welded in the welding hole 21. 2. Welding smoke will be generated during the welding process. The exhaust pipe 4 is used to exhaust air to make the collecting chamber 22 in a negative pressure state, so that the air in the welding hole 21, the collecting chamber 22 and the insertion hole 23 is diverted toward the exhaust pipe 4, so that the welding smoke generated inside the welding platform 2 can be extracted in time, so as to realize the controllable collection of welding smoke and prevent the welding smoke from directly entering the atmosphere.
