The clamping unit presses the workpieces to be welded against one another. The workpieces are inserted in part-specific cavities on the drawer. The upper clamping plate moves down by pneumatic or electric actuation and presses the workpieces together. The upper clamping tool can be a transparent glass plate, a metal frame with part-specific cutouts for the laser beam, or a combination
of both.
For process and quality control the clamping unit can be equipped with travel or force sensors. The clamping travel can be monitored with the distance measurement capability. In the simultaneous or quasi-simultaneous process type
also, the travel during welding can be measured, analyzed, or used for direct process control.

Clamping units for parts larger than described above are always individually designed and constructed.
In addition to the clamping unit, we also offer part-specific cavities and clamping tools such as clamping glass or clamping frame.
