Operating principle

Coating layer is removed byabsorbing the focussed laserpower

Very powerful but short laserpulses (with up to 450kW peakpower) cause very little thermalinfluence on the substrate

Metal substrate reflects laserradiation, removal process stops

Metals can not be damaged ormelted with the correct laser

parameter

Two physical effects: Coating layer is vaporised

(ablation by sublimation)

Productivity

Rule of Thumb: The darker and thinner the

contamination or paint, the easier it is to remove.

- Color, chemical composition andthickness of the target layer have adirect impact on the effectiveness

of the process.

- Often only on-site tests candetermine the effectiveness.Automated On-Line Cleaning of
