Laser paint removal

A clean surface – this is the basic requirement for successful and durable welding and adhesive connections. However, before joining, components often have paint and functional layers. The laser provides a remedy for this: the non-contact tool frees components of functional layers within seconds. And it does this only in areas where joining is meant to take place, for example, or where the functional layer is no longer needed. Here's how it works: pulses with high peak pulse power evaporate the wafer-thin layers, without affecting the component. Subsequent processes such as joining can then be carried out faster and more homogenously, and are entirely reproducible. The connections are clean and last longer. Joining preparation work using light as a tool can also integrate seamlessly into industrial series production, due to the fact that data can be easily transferred via interfaces. TRUMPF offers a special integration package for uncomplicated laser equipment integration for cleaning and paint removal in robot systems.

How does the laser paint removal process work?

Laser paint removal or ablation is a process during which functional layers are selectively removed from a surface using laser radiation (usually pulsed). The absorbing material is heated by laser energy and evaporates or sublimates.

The transparent material is ablated in its solid state. Geometrically defined sections are made accessible for subsequent processes (welding, bonding, screwing, sintering, contacting, etc.).

The laser radiation hits the workpiece surface.

The laser radiation heats the material.

The coating is removed by abrupt evaporation, sublimation or ablation.

The process products are removed using suction.
