BEO D70 multifocus optics
Multifocus option for BEO D70

The multifocus option for BEO D70 optics in combination with BrightLine Weld provides the innovative solution for media-tight weld seams. The laser beam is divided into four individual beam points on the workpiece. The result is a robust and stable welding process with improved weld quality thanks to fewer pores, spatter and crack formation. At the same time, you can make use of greater welding depth.

Laser: TruDisk
Laser power: up to 16 kW

Programmable motor focusing
Programmable motor focusing

The motor positioning of the collimator lens means that the focus point can be conveniently set in the Z direction. Modifications can be entered either directly by way of the laser control system TruControl or by way of an external machine control. Applications for which the focal position must be frequently changed can therefore be performed without additional effort.

Schutzglas- und Leistungsmesskassette
CCD camera

The CCD camera monitors the process at the processing point, and enables convenient setup of the laser process. It is the basis for process monitoring.

Focusing optics with Crossjet

Crossjet is a compressed air flow that runs orthogonally to the laser beam. It diverts contamination and spatter, extending the protective glass service life. The optics are more robust and the laser process is more reliable.

Focusing optics with Crossjet
MDE nozzle (metal vapor effect nozzle)

To make your welding process more efficient, you can add, in addition to the crossjet, the airflow from the metal vapor effect nozzle (MDE nozzle). The airflow keeps the metal vapor torch that arises while welding constant and therefore the energy brought into the material. This stabilizes the welding depth for precise laser processing. You also reduce your costs through a longer service life for your protective glass.

Shielding gas nozzle
Shielding gas nozzle

For high-quality welding results, a separate nozzle supplies shielding gas. This results in less oxidation of the weld seam. You can choose from various nozzles: aerator nozzle or linear nozzle.
