LASER MARKING OF METAL MATERIALS

Abstract

The contribution deals with the implementation of new information from the area of laser marking processing. The marking of various types of metal and non-metal materials are very actual topic of these days. The focus is on the production technical aspects of laser engraving and the introduction of processing strategies. Less attention is paid to the complex chemical process that can be observed when using laser as a tool chance the visible material appearance. The aim is to identify the parameters and guidelines that can be used to control the laser engraving process in the production environment. The problem of engraved metal material surface is discussed in solved experiments. The aim of the contribution is visual and microscope evaluation, how by changing of laser parameters can chance the influence on the final visage of tested metallic materials.
