Surface processing with the laser

Laser hardening is predestined for partial hardening, but is also suitable for softening. Advantages: it therefore also enables the processing of irregular 3D workpieces and creates little post-processing work.

Components often become contaminated, oxidize, or are covered in protection layers prior to the joining process. The laser provides a remedy for this: the non-contact tool frees components of dirt as well as oxidation and protection layers within seconds.

The laser generates regularly arranged geometries during structuring. The individual elements in such structures often measure only a few micrometers. For example, this type of laser structuring is suitable for adhesive bonding preparation or metal-plastic connections.

The laser frees components from paint and functional layers to create a clean surface. The laser, for example, is only used in areas where seams will be joined or the functional layer is no longer required.

Laser metal deposition is a generative manufacturing method. The applications of laser metal deposition range from coatings for wear and corrosion protection to component repair and joining processes and generation of complete components.

Laser markings score highly thanks to their consistency and very high contrast: compared to many conventional marking procedures, surface markings with lasers are always easily legible as well as chemically and thermally resistant.

In micro-production, short-pulse and ultrashort pulse lasers are used wherever controlled, highly accurate, and reproducible processing is required.

With VCSEL heating systems, surfaces can be precisely processed with direct heat treatment. You benefit from high process speed and irradiance in processes such as welding, drying, soldering, sealing or joining.
