Description

Technical Field

[0001] The utility model belongs to the technical field of welding, and in particular relates to welding equipment used in steel structure engineering. Background Art

[0002] As modern construction projects develop towards large spans and super-high-rises, steel structures have become an important structural form in the field of modern construction due to their advantages such as high strength, light weight, and fast construction speed. Welding, as the core process of steel structure manufacturing, plays the role of connecting steel into an overall structure.

[0003] Chinese patent CN220407595U discloses a welding device for steel structure, including a base and a support seat, a limit assembly, an adjustment assembly, a limit plate, an installation cavity and a guide block. When welding the steel structure, the steel structure is placed between the limit plates, and the steel structure is clamped and fixed by the installed limit assembly, thereby improving the stability of the steel structure. After the steel structure is fixed, the installed adjustment assembly drives the steel structure fixed by the limit plate on one side of the vertical plate to move toward each other, so that the two steel structures to be welded move toward each other and fit together. At this time, the installed telescopic member drives the welder to move toward the side close to the steel structure, so that the welder welds the steel structure. After the welding is completed, the installed telescopic member drives the welder away from the steel structure, which is convenient for removing the device, thereby improving the practicality of the device. However, the harmful gases such as carbon monoxide, nitrogen oxides, and metal oxides generated during the welding process of this patent cannot be effectively treated, resulting in long-term exposure of welding workers to a high-concentration pollution environment, which damages their health.
