Abstract:
A method for study of influence of step onto contrast of laser marking of samples of structural steel 1CS60, was developed. Experiments with fiber laser, working in the near infrared area, were conducted. A raster way for marking is used. The contrast for different values of step and power density, is determined. Graphs on the dependence of contrast from step for three power densities, were drawn. The obtained results were analyzed and summarized.
