FAIRINO Collaborative Robot (Cobot) Systems: The New Automation Trend in the Welding Industry

In the context of modern manufacturing, shifting towards Flexible Automation solutions requires equipment that is not only safe but also achieves high industrial precision. FAIRINO Robots has affirmed its position as a leading cobot solution provider thanks to its strategy of complete autonomy in the core component ecosystem and the intensive application of Artificial Intelligence (AI) in welding technology.

1. Enterprise Overview and the “FAIRINO EVERYWHERE” Philosophy

Origin and Strategic Vision

FAIRINO (Fair Innovation (Suzhou) Robot System Co., Ltd.) is headquartered in the Suzhou High-Tech Zone, Jiangsu Province – one of China’s most advanced manufacturing hubs. With supporting production facilities in Shandong, FAIRINO possesses a significant industrial production scale to meet global demand.

The “Democratization” of Robotics Philosophy

The slogan “FAIRINO EVERYWHERE” reflects the ambition to liberate labor from repetitive and hazardous tasks. Instead of being just a hardware vendor, FAIRINO positions itself as a provider of “comprehensive intelligent system solutions”, combining robotic arms, AI, Machine Vision, and Autonomous Mobile Robots (AMR).

2. Competitive Advantage: In-house R&D and Vertical Integration

For a 6-axis robot, the cost of core components (reducers, servo motors, control systems) accounts for up to 70% of its value. FAIRINO’s autonomy in manufacturing these components brings two strategic advantages:

Cost Leadership: Eliminating intermediaries allows FAIRINO to offer extremely competitive pricing, enabling Small and Medium Enterprises (SMEs) to easily access automation.
Superior System Performance: Absolute synchronization between mechanical design and control algorithms reduces latency, increases stability, and enables multi-axis linkage without the need for additional PLCs.

3. Control Technology and Real-time Synchronization

FAIRINO applies the EtherCAT Bus architecture, allowing high-speed data communication between the controller and the welding power source:

TCP Synchronization: Simultaneously controls the Tool Center Point (TCP) trajectory and welding source parameters (current, voltage, pulse frequency).
Heat Input Control: Ensures stable thermal energy across the entire weld seam, which is particularly critical when welding aluminum alloys and stainless steel.

4. Intelligent Welding Process Package

To handle complex variables in real-world welding, FAIRINO integrates advanced algorithms:

Swing Welding (Weaving): Supports sine, zigzag, circular, and L-shaped trajectories… helping to control the weld pool and fill large gaps.
Arc Tracking: Automatically corrects the trajectory based on the actual deformation of the workpiece through direct arc sensors.
Wire Positioning (Touch Sensing): Uses the welding wire as a contact sensor to determine workpiece coordinates, automatically compensating for fixturing deviations.
Seam Overlap (Recovery Programming): Automatically calculates the overlap point when an interruption occurs, ensuring weld continuity.

5. AIRLab Platform: Computer Vision and Artificial Intelligence (AI)

The AIRLab platform optimizes Small Batch Production:

3D Sensors & Point Cloud: Scans point clouds to recognize weld grooves without manual point programming (teaching).
Automated Planning: AI calculates the optimal torch angle and trajectory, minimizing preparation time.

6. Software Ecosystem and Flexible Programming Methods

FAIRINO provides 4 approach methods suitable for all user levels:

Graphical Programming: Intuitive drag-and-drop interface for beginners.
Node Graph Programming: Visualizes complex data flows and logic as connected nodes.
Scripting Languages (L Language/Lua): For experts requiring deep intervention in algorithms and custom socket communication.
Drag-to-Teach: “Zero-gravity” mode allows direct handling of the robot head to quickly record waypoints.

7. Specialized Industrial Accessories

Push-Pull Torch: Lightweight (1.1kg), ensuring stable wire feeding for aluminum welding with cables up to 20m long.
Smart Tool: A handheld robot teaching device integrated with hotkeys to record points and activate Macros directly at the torch.
3D Cable Management (Drag Chain): Specialized design protecting lines from twisting and abrasion.

Conclusion

With a combination of durable hardware and intelligent software, the FAIRINO cobot system is not just a labor replacement device but a solution that helps businesses achieve quality consistency according to industrial standards.
