[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1. During the welding process of steel structures, the air pump sucks the inside of the cavity, and the suction airflow sucks the area around the steel structure through multiple slots. The welding slag generated during the welding process of the steel structure is guided into the cavity through the slots by the suction airflow, and the welding slag in the airflow is filtered and collected by the filter.

The side wall of the shell 003 is provided with a plurality of holes 302 in a rectangular array, and the holes 302 are connected to the cavity 301. A cooling pipe 303 is provided inside the cavity 301. The welding head 203 adopts a laser welding head. The operator places the steel structure on the upper end of the base 001, and the two clamps 11 2 slides relative to each other, clamps and fixes it, and the movable block 202 slides horizontally, so that the welding head 203 moves to the top of the gap of the steel structure to be welded, and the laser beam emitted by the welding head 203 is used to weld the required weld seam. As the gap of the steel structure to be welded moves in the direction, the bracket 002 drives the welding head 203 to slide, and the gap of the steel structure to be welded is completely welded. During the steel structure welding process, the air pump 102 sucks the inside of the cavity 101, and the suction airflow sucks the surroundings of the steel structure through multiple notches 105. The welding slag generated during the steel structure welding process is guided into the cavity 101 through the notch 105 by the suction airflow. At the same time, the suction airflow drives the airflow around the steel structure to cool the steel structure during the welding process. The air pump 102 transports the airflow inside the cavity 101 to the inside of the chamber 106. The airflow inside the chamber 106 flows into the cavity 301, and then the airflow is cooled to an appropriate temperature through the cooling pipe 303. The cooling airflow is sprayed around the welded steel structure through multiple holes 302, thereby cooling the steel structure.

[0023] A plate frame 103 is slidably connected to one side of the base 001, and a filter screen 104 is fixedly connected inside the plate frame 103. The filter screen 104 is located inside the cavity 101, and the welding slag in the air flow inside the cavity 101 is filtered and collected through the filter screen 104.

The two clamping plates 112 slide relative to each other to clamp and fix the steel structure. The movable block 202 is pushed to slide horizontally by the hydraulic cylinder 201, so that the welding head 203 moves to the top of the gap of the steel structure that needs to be welded, and the laser beam emitted by the welding head 203 is used to weld the required weld seam. As the gap of the steel structure that needs to be welded moves in the direction of the gap, the motor 108 drives the screw 109 to rotate, so that the bracket 002 drives the welding head 203 to slide, thereby completely welding the gap of the steel structure that needs to be welded.

[0029] During the steel structure welding process, the air pump 102 sucks the inside of the cavity 101, and the suction airflow sucks the surroundings of the steel structure through multiple slots 105. The welding slag generated during the steel structure welding process is guided into the cavity 101 through the slots 105 by the suction airflow, and then the welding slag in the airflow is filtered and collected through the filter 104. At the same time, the suction airflow drives the airflow around the steel structure to cool the steel structure during the welding process.

[0030] The filtered airflow inside the cavity 101 is transported to the inside of the chamber 106 through the air pump 102. The airflow inside the chamber 106 flows into the inside of the cavity 301, and then the airflow is cooled to an appropriate temperature through the cooling pipe 303. The cooling airflow is sprayed around the welded steel structure through multiple holes 302, thereby cooling the steel structure.
