With the development of the steel structure industry towards scale and high-end, traditional processing technologies can no longer meet the requirements of precision, efficiency and environmental protection. Laser processing, with its core advantages of high precision, high efficiency and environmental protection, fully covers the entire process of steel structure processing, from plate cutting and profile processing to component welding, providing an efficient, precise and environmentally friendly full-chain solution for the steel structure industry, promoting the industry's transformation towards intelligence and greenization, and helping enterprises enhance their core competitiveness.

Core Applications: Laser Empowers the Four Core Links of Steel Structure Processing

Laser technology deeply penetrates the entire steel structure processing chain, providing customized and efficient solutions for the four core links of flat cutting, profile cutting, pipe cutting and welding, balancing processing precision and production efficiency, and adapting to various steel structure processing scenarios.

I. Laser Flat Cutting: The Efficient and Precise Choice for Steel Structure Plate Processing

As the basic core link of steel structure plate processing, laser flat cutting has the following core advantages:

• Wide Adaptability: Suitable for various common base materials of steel structures such as carbon steel, stainless steel and high-strength low-alloy steel, covering plates of different thicknesses from 1mm to 40mm, and can perfectly replace traditional flame and plasma cutting processes.

• Ultra-High Precision: Relying on high-power laser equipment and intelligent CNC systems, the movement precision of the cutting head reaches ±0.03mm, and the dimensional error is controlled within ±0.5mm, which is far superior to national standard requirements.

• High-Quality Processing: Non-contact processing with a heat-affected zone width of ＜0.3mm, avoiding plate deformation and edge burrs, and can enter the subsequent process without secondary grinding.

• Efficient and Energy-Saving: Equipped with an intelligent nesting and waste recycling system, the material utilization rate is increased to more than 80%, the loss rate is ≤1%, and it can operate continuously and automatically for 24 hours, with efficiency 2-3 times that of traditional processes.

II. Laser Profile Cutting: A Flexible Solution for Complex Section Steel Processing

Aiming at the processing of various section steels in steel structures, laser profile cutting has the following core advantages:

• Integrated Functions: Integrates full functions such as cutting, hole making, beveling, marking and labeling, eliminating the need to replace molds or tool heads and simplifying the processing procedure.

• Convenient Programming: Supports CAD/CAM software programming or direct import of TEKLA 3D modeling data to quickly complete complex profile processing.

• Flexible Adaptability: Can process various section steels such as H-beams, channel steels, angle steels and square steels, adapt to different specifications, and meet the needs of small-batch and multi-variety customized production.

• High-Quality Processing: Non-physical contact cutting, with smooth and flat cutting surfaces and no slag hanging, stable precision, ensuring the adaptability of profile splicing and welding.

• Cost Reduction and Efficiency Improvement: Reduces subsequent processing procedures, improves processing flexibility, and helps enterprises reduce labor costs and improve production efficiency.

III. Laser Pipe Cutting: A Precise and Efficient Breakthrough for Pipe Truss Processing

Aiming at the processing of pipe components such as steel structure pipe trusses, laser pipe cutting has the following core advantages:

• Strong Adaptability: Can process various pipes such as round pipes, square pipes, rectangular pipes and special-shaped pipes, adapting to the processing needs of various pipe components such as steel structure pipe trusses and wind power towers.

• Stable Precision: Adopts a multi-chuck flexible clamping system to accurately control the cutting angle, length and hole position, with the hole position tolerance stably controlled at ±0.1mm, ensuring precise docking of pipe splicing and welding.

• Efficient and Convenient: Can realize automatic loading, unloading and continuous processing of pipes, without the need for subsequent trimming, and the processing efficiency is more than 3 times that of traditional processes.

• Cost Saving: Reduces material loss, adapts to complex cutting needs such as large-span pipe truss nodes, and provides a solid guarantee for component assembly.

IV. Laser Welding: Dual Improvement of Quality and Efficiency in Steel Structure Component Connection

As the core process for connecting steel structure components, laser welding has the following core advantages:

• Outstanding Efficiency: Adopts laser-arc hybrid welding technology, no bevel is required for plates below 16mm, and only a small Y-type bevel is needed for plates above 16mm, with welding speed 2-3 times that of traditional processes.

• Controllable Cost: Reduces welding wire consumption cost by 73%, reduces labor input, and significantly lowers the overall welding cost.

• Excellent Quality: Low heat input, minimal thermal deformation of components, no need for post-correction; uniform weld formation, fine grains, joint strength increased by more than 25%, defect rate reduced by 80%, and qualification rate up to more than 98%.

• Strong Adaptability: Equipped with a visual sensing + AI adaptive control system, which can adjust parameters in real time to cope with gap fluctuations, adapt to the welding of complex components such as H-beams and box columns, and is widely used in high-end steel structure projects.

The efficiency of laser processing is 2-5 times that of traditional processes, which can shorten the production cycle, improve processing and welding quality, and reduce rework; it reduces material, labor and energy consumption costs, with a comprehensive cost reduction of 15%-70%, and is environmentally friendly, in line with the "double carbon" goal, helping enterprises achieve green and intelligent transformation. It is widely used in steel structure scenarios such as construction, bridges, wind power and nuclear power, providing enterprises with full-process precise processing support and promoting the high-end and large-scale development of the steel structure industry.
