I. Intelligent Welding of Steel Structures

Steel structures are mainly used in industrial and public construction projects. Supported by national policies and increasing industry recognition, the rapid development of China’s steel structure sector has been strongly boosted. According to a research report by CITIC Securities, the penetration rate of steel structures is expected to keep rising, with the industry demand CAGR reaching 5.4% by 2035.

Welding is a critical processing technology in steel structure manufacturing. Driven by policy support, the demand for steel structure processing continues to expand. Factors such as the shortage of welders and higher quality requirements have created an urgent need for welding robots. However, welding of non-standard steel structures remains a major challenge in automated welding technology.

Given the non-standard, small-batch welding demands of the steel structure industry, and supported by increasingly mature technologies including 3D vision, welding robots are evolving toward intelligence. This trend will promote the industrialization of non-standard steel structure processing.

II. Inspection Requirements

• Inspection Item: Welding guidance and positioning

• Workpiece Size: 300mm (L) × 150mm (W) × 100mm (H)

• Accuracy Requirement: 0.5 mm

• Speed Requirement: 200 mm/s

III. Solution

The Shenshi Intelligent 3D laser profilometer SR7400 is used to scan steel components and obtain profile images. The host computer acquires workpiece coordinates and weld seam coordinates through software algorithms, plans the welding path, and issues welding process parameters and compiled welding programs. After manual confirmation, the program can be started to begin welding.

The SR series of Shenshi Intelligent 3D laser profilometers adopts 3D precision trajectory guidance technology, enabling welding robots to perform welding operations accurately. It also inspects welding quality based on multiple process standards, providing an efficient and precise welding guidance and defect detection solution for the steel structure industry. This helps enterprises improve production capacity, reduce costs and increase efficiency.
