Инженерно-прогнозен анализ чрез числени експерименти на лазерното маркиране на стомана С22
Engineering-predictive Analysis Through Numerical Experiments of Laser Marking of С22 Steel

Summary/Abstract: Numerical experiments have been conducted for the laser marking process of C22 structural steel samples. The influence of power density and speed on the process has been studied through numerical experiments. The research concerns a fiber laser, an innovative laser operating in the near infrared region. Temperature fields in the impact zone have been obtained for different power densities and speeds. The results of the numerical experiments have been analyzed and summarized. Preliminary working intervals of power density for three speeds and speed for three power densities have been determined for the processes of laser marking by melting and laser marking by evaporation. The findings contribute to the development of technological tables for industrial laser marking and provide practical guidance for technologists and operators of laser processing systems
