[0002] As we all know, high-strength steel structural components refer to a collection of components made of high-strength steel and used to construct various engineering structures. Laser welding technology is an advanced welding method that uses a high-energy-density laser beam as a heat source to achieve material connection.

The invention patent with Chinese patent application number CN202210154585.7 discloses a laser welding device for high-strength steel structure components, which is roughly described as including a laser welding device, a collecting box is provided on the lower right side of the laser welding device, a connecting rod is fixedly installed on the upper end of the collecting box, a support plate is slidably connected through the upper side of the connecting rod, the left end of the support plate is fixedly connected to the laser welding device, a spring 1 is sleeved on the connecting rod, and the upper and lower ends of the spring 1 are respectively fixedly connected to the support plate and the collecting box, a cleaning roller is rotatably connected to the upper side of the right end of the collecting box, the lower end of the cleaning roller and the lower end of the collecting box are located on the same horizontal line, a scraper is provided on the lower left side of the cleaning roller, the right end of the scraper is in contact with the cleaning roller, and a magnetic rotating plate is provided on the lower side of the scraper. When in use, the provided collection box is convenient for collecting impurities scraped off by the scraper to prevent the impurities from falling on the surface of the steel structure again.

[0004] Although the technical solution of the above-mentioned existing steel bracket assembly can realize the application of the bracket, the connecting part thereof is mainly assembled by bolt assemblies, and the structural stability needs to be further strengthened. If welding is used to realize the connection and assembly of the steel structure, the above-mentioned laser welding device of a high-strength steel structure assembly can be used for welding and fixing the connecting part of the steel structure, but the welds between the parts of the steel structure are mostly formed by adding reinforcing ribs to improve the structural strength, and the reinforcing ribs are mostly welded directly relative to the steel structure, which will inevitably cause the effective welding position to be too narrow, and the structural strength of a single reinforcing rib needs to be further strengthened. The addition of multiple structural reinforcing ribs will also cause too many weld parts, reducing production efficiency. Summary of the invention

[0014] Preferably, the first transverse connecting member, the second transverse connecting member, the first vertical connecting member and the second vertical connecting member are all provided with a plurality of secondary reinforcing ribs.

[0015] A laser welding process for high-strength steel structural components comprises the following steps:

[0016] S1. When in use, first form a relative position alignment between the horizontal steel frame and the vertical steel frame, then place the first horizontal connector and the second horizontal connector relative to the horizontal steel frame, and use laser to complete the relative welding connection between the first horizontal connector and the second horizontal connector.

After the structural reinforcement rib frame (3) has achieved structural stability relative to the horizontal steel frame (1) and the vertical steel frame (2), further welding operations are performed on the overlap between the first horizontal connecting member (4) and the horizontal steel frame (1), the overlap between the second horizontal connecting member (5) and the horizontal steel frame (1), the overlap between the first vertical connecting member (6) and the vertical steel frame (2), the overlap between the second vertical connecting member (7) and the vertical steel frame (2), the overlap between the first horizontal connecting member (4) and the structural reinforcement rib frame (3), the overlap between the second horizontal connecting member (5) and the structural reinforcement rib frame (3), the overlap between the first vertical connecting member (6) and the structural reinforcement rib frame (3), and the overlap between the second vertical connecting member (7) and the structural reinforcement rib frame (3).
