You can rely on our experts, trust us to always have the best solution in mind for your production tasks and know that we will advise you independently of any preferred technologies.

You can adapt your focusing optics to any job with the large number of options. You can also receive special optics for laser metal deposition with powder feed, or for linear laser spots.

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 12kW

Fixed optics that can be combined with the TruDiode
Programmable motor focusing

Thanks to motor positioning of the collimator lens, the focus point can be conveniently set in the Z direction. Modifications can be entered either directly via the laser control system TruControl or via an external machine control. Applications for which the focal position must be frequently changed can therefore be performed without a great deal of additional effort.

Protective glass and power measurement cassette
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.

Protective glass and power measurement cassette
Protective glass and power measurement cassette

During operation and when changing the protective glass, the seal and interior ventilation of the protective glass prevent contamination. Changing the protective glass itself is quick and easy without tools. In place of the protective glass cassette, you can also insert a power measurement cassette. This enables you to easily check the laser power.

Crossjet option, TRUMPF focusing optics
Crossjet

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

The metal vapour effect (MDE) nozzle stabilises the welding process.
MDE nozzle (metal vapour effect nozzle)

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

Technology-Picture-laser-welding-machines
Shielding gas nozzle

For high-quality welding results, a separate nozzle supplies shielding gas. The welding seam thereby oxidises less. You can choose from various nozzles: aerator nozzle, linear nozzle or multiple pipe nozzle.
