YAG with a radiation wavelength of λ=1064nm, exposure time τ = 5-10 ns, and a repetition frequency of 1-10 Hz, the radiation power density and coverage degree were varied. Using the laser ablation effect, thin (a few micrometers) paint coatings were removed with very high precision. Preliminary laboratory tests confirmed the high utility of laser technology in automotive painting.Nowadays, a clean car body surface is an essential element in the process of preparing it for the application of paint coatings. To obtain the required coating adhesion, it is necessary to properly prepare the surface by, for example, removing corrosion, oxides, and all contaminants, and creating an appropriate roughness profile on the surface.
