Description

Technical Field

[0002] In recent years, the development momentum of steel structure buildings has been rapid, showing significant advantages in environmental protection, energy saving, high efficiency and factory production. Compared with traditional brick-concrete structure buildings, steel structure buildings use construction steel to build load-bearing structures. These structures are usually composed of beams, columns, trusses and other components made of steel and steel plates, and the components are connected by welds, bolts or rivets. As one of the most industrialized building forms, steel structure not only improves construction efficiency, but also promotes the effective use of resources.

[0003] In the manufacturing process of steel structures, welding is a key step to connect multiple metal parts together to form a complete structure. Traditional manual welding methods rely on the experience and skills of welders. Although they are more flexible, they have problems such as low efficiency, difficulty in quality control, high labor intensity and high cost. With the continuous improvement of industrial automation, automatic welding equipment has gradually replaced some manual operations. Especially in large-scale production, the application of automatic welding equipment has significantly improved production efficiency and product quality.

[0004] However, existing automatic welding equipment still faces many challenges when dealing with steel structures with complex shapes or different specifications: 1) For steel structures that need to be butted, existing equipment may not be able to ensure the reliable positioning of the welded parts, resulting in welding position deviation, affecting the quality and safety of the final product; 2) When faced with welded parts of different sizes, shapes or angles, traditional welding equipment is difficult to adjust and cannot respond quickly to changing needs, limiting its scope of application; 3) Most automatic welding systems can only perform welding tasks in fixed modes, such as single-sided welding or continuous welding in a single direction, and lack support for multi-angle and multi-directional welding, especially when simultaneous welding on both sides or staggered welding is required; 4) Some welding solutions fail to integrate multiple processes such as conveying, positioning, and welding well, and have shortcomings.
