Abstract :
The technological possibilities of the article marking by means of a fibro solid-body laser are considered in the paper. The analysis of the technological regimes and defects of precision laser marking has been conducted. One of the causes lowering the quality of laser seam - a low reliability of the system machine-device-instrument-detail for the technological equipment - has been determined. The authors of the paper consider the problem of laser marking of the articles made of plastic, which are covered by thin metal and electro-conductor coating.
