Laser welding services

Laserschweissen für Medizin und Sensortechnik

Welding seams with pinpoint accuracy — even on hard-to-reach workpieces. If your components are too large to transport, we will even weld at your site.

Compared to TIG or MIG/MAG welding, laser welding offers a few other advantages:

  • extremely thin welds possible without reworking
  • Heating of the workpiece localized
  • Joining of metals with different melting point possible
  • Machining of very thin workpieces possible
  • easily reproducible

We use the processes of pulsed laser welding and CW laser welding.


Pulsed laser welding

With the pulsed laser welding process, the energy feed is sent at time-limited intervals. After each laser pulse, there is a short pause, during which the previously created melt can cool off. This fine welding process is especially suitable for thin-walled workpieces, for connecting components with very different geometries and for hard-to-weld materials.

 

CW laser welding (continuous wave)

With our new AL-TW 900F fiber laser, we can work in continuous wave (CW) mode. In contrast to pulsed laser welding processes, there is a continuous energy feed during the process. The possible welding penetration depth is 3 mm.
The images show a deep welding application on a stainless-steel flange assembly. Typical of these laser welds are the uniform root formation and weld seam surface.


Where can laser welding be used well?

The possible applications of laser welding technology are myriad. From joint welding of bellows to connection fittings, complex vacuum technology assemblies and antenna system components, the applications never end.

Tool and mold manufacturing

Traditional applications in laser welding and tool and mold manufacturing include:
• Contour changes
• Correcting worn component geometries
• Repairing and modifying mold inserts
• Repairing die casting molds
• Removing discontinuities in castings
• Substitution of heavily used functional areas
and much more.

 

Precision, medical and sensor technology

In manufacturing plate heat exchangers and other multilayer assemblies, we use the LAfet® laser wire feed system with continuous weld metal output of the finest quality.

We work with materials typical in medical technology, such as titanium and fully austentic, highly corrosion-resistant stainless steels, as well as platinum, tantalum and other noble metal alloys.

Components for media-carrying systems in the aeronautics industry and many different applications in sensor technology round out the manufacturing portfolio.


Note on laser protection:

The basis for working with laser equipment is UVV BGV B2 (VBG 93) – Laser radiation.
This applies to creation, transfer and use of laser radiation, and compliance during maintenance, adjustment and repair work. Most important in laser beam protection is protection of the eyes against laser radiation, because eye damage is irreparable. We will be happy to advise you on protection measures and laser protection equipment. Just ask us!
