Apstrakt:
Studies relate to two basic methods of marking of steel - by melting and by evaporation. Based on theoretical considerations are determined preliminary intervals of power density for the laser marking of steel 50ChN. Experiments are realized with a 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 drawn. Working intervals of the power density for marking by melting and by evaporation for visual perception of the marking and using the readers were defined.
