The workpiece positioning fixture 1 is provided with a welding bin 11 and an air inlet 12, the welding bin 11 is opposite to a welding area of the workpiece 3 to be welded, the air inlet 12 is arranged on the periphery of the welding bin 11 and communicated with the welding bin 11, and the air outlet direction of the air inlet 12 is inclined upwards. The dust hood 2 covers the workpiece positioning fixture 1, a laser light-emitting nozzle 21 and a suction opening 22 are arranged on the dust hood 2, the laser light-emitting nozzle 21 is located above the welding bin 11, the suction opening 22 is arranged around the laser light-emitting nozzle 21, the suction opening 22 is communicated with the air inlet 12 through the welding bin 11, and the suction opening 22 is externally connected with a negative-pressure dust suction device.
In the embodiment, the workpiece positioning fixture 1 clamps the to-be-welded part 3 and locks a required welding area, the dust hood 2 and the workpiece positioning fixture 1 are arranged oppositely, the laser light emitting nozzle 21 welds the welding area, and welding slag splashed in the welding process can be pumped away by the negative pressure dust pumping equipment under the combined action of air flow entering the air inlet 12 and air flow pumped by the air pumping opening 22.
