Problems solved by technology

[0002] At present, the design requirement of U-shaped rib fillet welds on most steel structures at home and abroad is that the welding penetration should reach more than 70%. However, to meet this requirement, the assembly process and welding process in the production process must be strictly controlled. The U-shaped rib fillet weld welding process of the welded steel structure leads to serious defects in the project, which cannot reach the designed service life, resulting in repeated construction or even scrapping throughout the year

Abstract

The invention discloses a full-penetration welding technology for fillet seams of a U-shaped rib plate of a steel structure. A steel top plate and the U-shaped rib plate form the steel structure with narrow space, a welding gasket is installed on an internal fillet seam inside the narrow space, an external bevel fillet seam outside the narrow space is welded, and one side welding and double side forming of the steel top plate and the U-shaped rib plate can be realized. According to the full-penetration welding technology, the fillet seams of the U-shaped rib plate can be effectively protected against weld penetration, full penetration of the fillet seams of the U-shaped rib plate of the steel structure can be guaranteed, the front sides and the rear sides of the fillet seams can be well formed, the fatigue resistance of the fillet seams of the U-shaped rib plate of the steel structure can be improved, and the service life of the steel structure can be prolonged.

Description

technical field [0001] The invention relates to the technical field of bridge and steel structure engineering manufacturing welding. More specifically, the present invention relates to a welding process for full penetration of fillet welds of U-shaped ribs in steel structures. Background technique [0002] At present, the design requirement of U-shaped rib fillet welds on most steel structures at home and abroad is that the welding penetration should reach more than 70%. However, to meet this requirement, the assembly process and welding process in the production process must be strictly controlled. The U-shaped rib fillet weld welding process of the welded steel structure led to serious defects in the project, which could not reach the designed service life, resulting in repeated construction or even scrapping throughout the year. Therefore, it is of great significance to seek a manufacturing process and supporting materials for the U-shaped rib fillet welds of steel struc...
