Abstract

Studies relate to two basic methods of steel marking − by melting and by evaporation. Based on theoretical considerations, preliminary intervals of power density for laser marking of 50 ChN steel are determined. Experiments are carried out with fiber laser, operating in the near infrared area. Graphics on the dependence of contrast of marking from the power density of laser radiation for two methods of marking were developed. Working intervals of the power density for marking by melting and by evaporation for visual perception of marking and using the readers were defined.
