Surface processing with TRUMPF lasers

Surface processing with the laser

Whether for hardening, coating, cleaning or structuring – the laser can process surfaces with different dimensions easily and quickly. This is possible thanks to a very wide range of different beam sources with laser powers and properties which can be set precisely.

The benefits of surface processing with the laser


The laser can be used with great flexibility, even in 3D, thanks to tool-free, non-contact processing – mechanical wear and tear is a thing of the past.


Whether steel, copper or aluminium – a great number of the most varied of materials can be processed with the laser as a tool.

Precise and reproducible

The laser facilitates a controlled, selective and precise process. Which means you benefit from reproducible results.

Less distortion

Due to the localised laser processing on the workpiece, basically no heat is applied to the workpiece, which greatly reduces any distortion in it.

Subdivisions of surface processing

Bending tool hardened with TruDiode
Laser hardening

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.

Laser cleaning with the laser
Laser cleaning

Components often become contaminated, oxidise, 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.

Laser structuring

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

Laser paint removal

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

Laser metal deposition (LMD)

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 marking with TRUMPF products
Laser marking

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.

Microprocessing with TRUMPF products

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

Laser heat treatment

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.
