[0033] Specifically, in use, the building steel structure parts are inserted into sealing cover main body 3 from open 4 to the appropriate position, then the sealing air bag 5 is inflated, so that it is inflated and tightly attached to the edge of the open 4 of the building steel structure and the sealing cover main body 3, forming a sealed space, and the welding gun is inserted into the sealing cover main body 3 from the fixed hole 6 to weld the building steel structure, which can significantly reduce the occurrence of slag inclusion and surface unevenness of the weld, and improve the overall quality of the weld.
[0034] Please refer to Figure 4 , sealing cover main body 3 includes
[0035] Fixed part 31, overall half arc cover structure;
[0036] The movable part 32 is matched with the shape and size of the fixed part 31, and is rotationally connected to the fixed part 31, and can be matched with the movable part 32 to jointly surround and fix the building steel structure to be welded.
[0037] Specifically,
[0038] The sealing cover body 3 is divided into a fixed part 31 and a movable part 32, which facilitates the placement of the steel structure to be welded into the sealing cover body 3.
[0039] During installation, the fixed part 31 is placed on one side of the steel structure, and then the movable part 32 is rotated to jointly surround the steel structure with the fixed part 31, thereby positioning and preliminarily fixing the steel structure, and preparing for subsequent sealing and welding operations.
[0040] Referring to Figure 4 , the fixed part 31 and the movable part 32 are both rotationally installed with a rotating part 33, which is in the form of a semicircular plate. When the fixed part 31 and the movable part 32 are combined, the two rotating parts 33 are butted to form a circular ring body, and the fixing hole 6 is formed on the rotating part 33.
[0041] The outer wall of the rotating part 33 is provided with teeth 34 distributed circumferentially, and the outer wall of the fixed part 31 is fixedly installed with a driving motor 35, and the driving end of the driving motor 35 is connected with a gear 36 engaged with the teeth 34.
[0042] Specifically,
[0043] The rotating part 33 is provided with teeth 34, the fixed part 31 is provided with a driving motor 35 and a gear 36 engaged therewith, the driving motor 35 drives the gear 36 to rotate, and then drives the rotating part 33 to rotate, which can realize automatic or semi-automatic operation, facilitate the adjustment of the position of the rotating part 33, and more flexibly adapt to different welding angles and position requirements during welding, thereby improving welding efficiency and quality.
[0044] When it is necessary to adjust the position of the rotating part 33, the driving motor 35 is started to drive the gear 36 to rotate, and the gear 36 interacts with the teeth 34 of the rotating part 33 to make the rotating part 33 rotate around its rotation center, thereby changing the position of the fixing hole 6 to meet the requirements of welding operation.

[0046] Specifically,
[0047] The outer wall of the fixed part 31 and the movable part 32 is provided with a limiting edge 37, and is fixed by a positioning bolt 38. This design can enhance the stability of the connection between the fixed part 31 and the movable part 32, ensure that the sealing cover body 3 will not be accidentally opened or loosened during the welding process due to external force and other factors, and ensure the sealing effect and the smooth operation of the welding operation.
[0048] After the movable part 32 is combined with the fixed part 31 to surround the steel structure, the two opposite limiting edges 37 are aligned, then the positioning bolt 38 is inserted and tightened, so that the fixed part 31 and the movable part 32 are firmly connected together, maintaining the stability of the overall structure of the sealing cover body 3.
[0049] Referring to Figure 4 , a through opening is formed in the outer wall of the rotating part 33, and a collection cover 8 is fixedly installed in the through opening. The collection cover 8 is provided with a detachable plug 9.

[0051] Specifically, the through opening is formed in the outer wall of the rotating part 33 and the collection cover 8 is installed. The collection cover 8 can be used to collect impurities such as smoke and slag generated during welding, so that the internal environment of the sealing cover body 3 can be kept relatively clean, avoiding the accumulation of impurities in the sealing cover body 3 to affect the welding quality, and also being conducive to protecting the health of the welding equipment and the operator.
[0052] During welding, the smoke and slag generated in the sealing cover body 3 are connected to the collection cover 8 by unscrewing the plug 9 and connecting the external negative pressure to the collection cover 8. Due to the action of airflow, the welding smoke will be guided into the collection cover 8, avoiding the presence of welding smoke in the sealing cover body 3 during welding.
[0053] It should be noted that:
[0054] After the welding is completed, the rotating part 33 is rotated to make the opening of the collection cover 8 downward. The collection cover 8 is in the shape of a conical funnel, and the small end is threadedly connected to the detachable plug 9. The slag generated during welding is collected in the conical funnel-shaped collection cover 8. When cleaning is needed, the threaded plug 9 is unscrewed, and the impurities are discharged from the small end of the collection cover 8. Then the part is screwed on for continuous use, which is convenient for cleaning the inside of the sealing cover body 3.

[0056] The welding table 1 is in the shape of a plate structure;
[0057] The support seat 2 is symmetrically arranged on the front and rear sides of the sealing cover body 3, and the support seat 2 is provided with an arc-shaped groove corresponding to the opening 4.
[0058] Specifically, the welding table 1 provides a stable plane support for the entire welding operation, ensuring the position stability of the steel structure during the welding process, the arc-shaped groove on the support base 2 corresponds to the opening 4 of the sealing cover main body 3, which can better support and position the steel structure, make the welding process more stable, and be beneficial to improve the welding precision and quality.
