Introduction

Steel structures are increasingly critical in various construction projects due to their high strength, short construction periods, and recyclability. However, the traditional manual welding process in steel construction is inefficient and labor-intensive, representing a significant bottleneck in the industry. The shortage of skilled welders is growing annually, making recruitment challenging and escalating labor costs. Although traditional welding robots have improved efficiency, most are programmed through a teaching method which is slow and requires high technical skills. This is not suitable for non-standard jobs or small batches, leading to repetitive teaching and inefficiency.

Recognizing these industry challenges, Han’s Laser has leveraged its commitment to independent research and technological innovation to introduce two intelligent arc welding robot workstations tailored for the steel structure industry: a ground rail robot workstation and a cantilever hanging robot workstation. These innovations address the traditional pain points in steel structure welding.

Ground Rail Steel Structure Robot Laser Welder Advantages

1.Efficient Layout

The robot features A/B positions on either side arranged as welding stations, enhancing space utilization.

2.Dual-side Welding

The robot can weld from both sides, reducing loading times and improving equipment operational efficiency.

3.High Productivity

Each side of the robot can arrange and simultaneously weld two components, significantly boosting welding efficiency.

Cantilever Hanging Robot Workstation Advantages

1.Multi-axis Configuration

Configurable with multiple external axes to achieve 7-axis, 8-axis, or 9-axis linkage.

2.Versatility

Capable of welding deep, large-scale products, adaptable to most welding scenarios including bridge steel structures, shipbuilding, and heavy industry.

Teaching-Free, More Intelligent

The seven-axis ground rail steel structure robot metal laser welding machine represents a highly automated intelligent welding solution. Installed on ground-level rail tracks, the robot can move along these tracks, thereby expanding its operational radius and applicability. The seventh axis is particularly useful in industries such as spraying, welding, handling, stacking, machine tool loading/unloading, smart storage, automotive, and aerospace.

This ground rail model spans a total length of 7900mm with an effective travel distance of 6000mm and can carry loads up to 1.5 tons. The combination of racks on the guide rails and precise servo motor control enhances movement accuracy. Capable of welding longer or larger workpieces, this system is not only convenient and practical but also offers flexibility, high precision control, and increased productivity and labor productivity. Additionally, it can operate in harsh and hazardous environments, replacing costly manual labor while reducing worker fatigue and enhancing production safety. Han’s Laser can custom design these seven-axis ground rail intelligent welding systems to meet various specifications and precision requirements.

The Foundation of Intelligent Arc Welding

The success of intelligent arc welding relies on advanced robotic systems, primarily composed of a digital twin system, control panel, robot body, automatic wire feeding device, and welding power supply. This setup automatically generates pathfinding and welding paths without the need for teaching. The digital twin system supports multi-layer and multi-pass continuous welding, corner welding, automatic pathfinding, seam tracking, breakpoint positioning, and collision detection. The application of intelligent welding technology is broad, encompassing automotive manufacturing, aerospace, construction, energy, chemical, maritime, and rail transportation sectors.

Conclusion

This technology marks a significant leap forward in addressing the growing needs of the steel construction industry, showcasing how innovation can lead to smarter, safer, and more efficient building practices.
