FAIRINO AIRLab
Enabling Robots to 'See' and Understand Welding Seams

From everyday furniture to national heavy machinery, welding has always been a key process in the manufacturing industry, especially in shipbuilding and steel structure industries. However, traditional welding methods often struggle to balance efficiency, quality, and flexibility when faced with challenges such as large components, non-standard parts, difficult-to-move workpieces, a wide variety of welding pieces, and high costs for production layout modifications. As a "Collaborative Robot Popularizer and New Scenario Application Pioneer," FAIRINO, guided by the philosophy of "AI + FAIRINO = REALITY," has deeply understood the pain points of the welding industry and is committed to reshaping the welding experience with AI. To this end, FAIRINO has launched the new generation FR3WML and FR3WMS collaborative robots, specifically designed for welding scenarios, offering the following core advantages:

► Lightweight and Flexible: Weighing ≤11kg, they can be lifted with one hand, making them easy to deploy and capable of handling various complex working environments.

► Technical Features: The end can rotate 360°, adapting to welding needs at different angles.

► Stable and Reliable: With an optional IP65 protection rating, they are dustproof, oil-resistant, and protected against water spray, ensuring stable operation in harsh environments.

FAIRINO is committed to building a more open and compatible ecosystem, offering an application model that Robot+, FAIRINO  Packages+, and Partner Ecosystem Modules. This model can seamlessly integrate with other equipment and systems, fully meeting the deep development needs of integrators and providing users with more comprehensive and efficient welding industry solutions.

02   FAIRINO Welding ProcessPackage 

       Opens a New Chapter in Intelligent Welding

FAIRINO robots fully understand the needs of specific welding scenarios and have developed a more comprehensive, easier-to-operate, and smarter-to-store FAIRINO welding process package. The automated welding equipment integrated with FAIRINO collaborative robots can quickly adapt to global mainstream welding machine brands and flexibly combine with extension axes, positioners, force sensors, etc. It supports various welding functions such as swing welding, arc tracking welding, wire positioning, and welding interruption recovery, as well as multiple welding processes like straight welding, segment welding, fillet welding, and multi-layer multi-pass welding.

① Swing Welding

FAIRINO robots support various swing shapes, including triangular wave, vertical L-shape, triangle, circle, oblique zigzag, and sine wave.

② Arc Tracking

When welding grooves such as right angles, U-shapes, and V-shapes, the robot calculates the position relationship between the welding gun and the groove center based on the welding current and voltage information after arc initiation, compensating for weld deviations in real-time to ensure precise weld position and stable welding quality.

③ Wire Positioning

Wire positioning detects the actual position of the workpiece in the robot's coordinate system by detecting changes in the electrical signal when the wire contacts the workpiece surface. After teaching the positioning path, the robot automatically finds the workpiece surface boundary. When the wire touches the workpiece surface, a voltage signal change occurs, and the welding machine communicates this signal back to the robot, which records the boundary position.

④ Welding Interruption Recovery

This function is used when welding is interrupted due to operator intervention, collisions, or arc breaks. The robot can re-ignite the arc from the interruption point and continue the welding task. When re-igniting, the robot automatically retreats a specified distance along the welding direction to overlap with the previous weld, ensuring welding quality.

03    FAIRINO Lightweight Push-Pull Welding Torch

        Ensures Excellent Welding Quality

FAIRINO welding robots are equipped with lightweight push-pull wire welding guns, capable of adapting to long-distance wire feeding needs. Whether in flat, vertical, or overhead welding positions on ship hulls, they ensure stable wire feeding, significantly improving welding efficiency. Uniform and stable wire feeding effectively guarantees welding quality.

► Ultra-Long Wire Feeding: Wire feeding hose extended to 20 meters.

► Goose Neck Quick Change: Simple operation for quick replacement.

► Compact Design: Weighs ≤1.1KG, lightweight and convenient.

► Wide Application: Suitable for long-distance and narrow-space welding scenarios in shipbuilding, bridge construction, and steel structures.
