Cantilever Welding Robot solution

Cantilever Welding Robot is a specialized automated welding system designed primarily for large-scale workpieces and structural steel components. Unlike standard industrial robots, the cantilever design features a horizontal arm extended from a vertical column, allowing the welding head to reach over large structures such as H-beams (HEB), boxes, and heavy plates.

Key Features and Advantages

• Large Working Envelope: The “overhanging” arm design provides a significant reach, making it ideal for long and wide workpieces that would be difficult to fit inside a traditional robotic cell.

• Space Efficiency: Since the robot is mounted on a single side (the cantilever column), it leaves the other side of the workspace open, allowing for easier loading and unloading of heavy materials via overhead cranes.

• High Versatility: These systems are often mounted on floor rails (linear tracks), enabling the robot to travel long distances—such as 12 meters or more—to perform continuous or intermittent welds along structural beams.

• Integration with Sensing Technology: Modern cantilever robots are frequently equipped with laser seam tracking and arc sensors to compensate for minor misalignments or thermal deformation during the welding process.

Common Applications

Cantilever welding robots are the workhorses of the heavy industry sector, specifically in:

1. Structural Steelwork: Welding of H-beams, I-beams, and complex truss sections.

2. Shipbuilding: Joining large hull plates and stiffeners.

3. Construction Machinery: Fabricating chassis for excavators, cranes, and trucks.

4. Bridge Construction: Welding of large-scale girders and support structures.
