OPTIMIZATION OF THE PROCESS OF LASER MARKING OF PRODUCTS MADE OF TOOL STEEL

L Lazov, N Angelov

Abstract


Special consideration is given to parameters affecting the contrast of laser marking on tool steel products and relevant experimental results are reported related to determining the critical density of laser radiation power in melting and evaporation of steel types У7 and Р6М5. The dependence of contrast on marking speed and power density is also presented.

Keywords


laser marking, tool steel, contrast.
