Description

Technical Field

[0001] The invention relates to the technical field of steel structure processing, and in particular to a welding device for steel structure processing. Background Art

[0002] Steel structure refers to a building or engineering structure constructed with steel as the main material. It is widely used in various construction projects due to its high strength, good ductility and plasticity. From high-rise buildings to bridges, industrial plants and even stadiums, steel structure has become an indispensable part of modern architecture due to its many advantages. In the process of steel structure processing, welding equipment is required to weld the steel structure.

[0003] The existing welding device for steel structure processing places the steel structure to be welded at a suitable position, and the traveling module drives the two steel structures to be welded and fixed to move towards each other, so that the two steel structures to be welded are butted, and then the welding head is driven close to the steel structure to be welded to weld and fix it. However, in actual use, when welding and fixing of medium or large-sized steel pipes are required, the staff needs to manually lift the two steel pipes to be welded onto the welding table or lift the two steel pipes to be welded onto the welding table through external lifting tools. After welding is completed, the welded steel structure is manually moved down or moved down through external lifting tools.
