Description

Technical Field

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

[0002] As an important part of transportation infrastructure, bridges and roads play an important role in urban development and people's travel. They can cross natural barriers and reduce mutual influence in traffic. Steel structure engineering is a structure mainly made of steel, which is one of the more common structural forms in modern construction engineering. Steel structure has the advantages of high strength, light weight, fast construction speed and good earthquake resistance, so it is widely used in large public buildings, industrial plants, bridges and other fields.

[0003] In the process of using steel structures to build bridges, it is often necessary to weld the steel structures. At present, when steel structure bridges on the market are welded, they are usually welded into semi-finished products in advance and then assembled. Once problems are found in the welding after arriving at the site, they are usually scrapped, wasting resources and time, and the efficiency of the operation is also reduced. Moreover, on-site welding can only be performed at the same position of the steel structure, and it is necessary to manually move the position to adjust the welding position or move the steel structure to adjust the welding position, which causes the steel structure bridge to shift in position when moving or causes safety accidents due to the focus on welding when personnel move, resulting in poor welding quality and low work efficiency.

DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
