8-Axis Cantilever Welding Robot Workstation

6 m and 13 m Configurations

The same 8-axis cantilever workstation is available in different configurations. The dimensions below describe two reference arrangements and must be read together with the corresponding layout and workpiece requirements.

How to read these dimensions: rail length, installation footprint and maximum workpiece dimensions are different measurements. A 13 m layout does not mean a 13 m weld length. Effective welding coverage also depends on torch access, fixtures and robot position. Confirm the configuration against your drawings before ordering.

8-Axis Cantilever Workstation FAQ

Are the 6 m and 13 m arrangements different models?

They are different configurations of the same workstation model. The 6 m figure describes the rail length in one arrangement; the 13 m figure describes the installation layout in the other. Compare each configuration using its own specifications.

Can the 13 m arrangement weld a 13 m-long component?

The reference project describes parts up to 12 m long. Layout length and usable workpiece length are different. Joint access, fixtures and robot reach must be checked for the proposed part.

Does programming-free welding remove all setup work?

No. Vision-based seam recognition supports path generation, but the application still needs suitable welding parameters, workpiece support and access checks. Model-based functions and equipment options depend on the selected configuration.

What information is needed to select a configuration?

Send representative drawings, overall part dimensions, material and thickness, joint details, the required weld positions and your available floor space. Include production requirements so the rail, cantilever arrangement and welding equipment can be checked for the intended job.
