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

Mit dem TruDiode kombinierbare Festoptik
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.

Schutzglas- und Leistungsmesskassette
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 functions quickly and easily 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.

Option Crossjet, TRUMPF Fokussieroptiken
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.

Die Metalldampfeffekt-Düse (MDE) stabilisiert den Schweißprozess
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.

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

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