laser welding head / pneumatic

of sheet metal packages one hundred percent reliability in focus guidance is an absolute must. This is ensured by the HIGHYAG RSK laser processing head. An integrated pressure roller or pressure finger clamps the workpiece and thereby simultaneously takes over the guidance of the focus position on the workpiece.

With an infinitely variable pneumatically controlled force (max. 100 daN), the roller or finger runs over the sheet metal package, thereby precisely following the shapes of the workpiece. Direct coupling of the pressure finger with the focus achieves an “auto-focus control”, which significantly simplifies the process set-up.

On the other hand, exerting counter pressure can also generate forces below the weight of the head, thus making a “weightless” welding process possible.

For clamping the sheet metal package on both sides, a clamping module with double rollers or double fingers is mounted on the pneumatic linear unit. This enables a clamping force of up to 100 daN to be achieved.


The proven focus heads BIO and BIMO, offering the advantages of a quick cover slide change and opto-electronic cover slide monitoring, are used for focusing the laser beam.

The modular design of HIGHYAG RSK with head-mounted EPS allows customer-specific system integration and robot adaptation (with or without a crash sensor), a wide application spectrum and versatile, long-term guaranteed possibilities for retrofitting. A high level of investment security is therefore guaranteed.
