Study of laser cutting of low-alloy steel with using various gases

Abstract

Based on the laser cutting of steel 09G2S, specific features of the power tool and its use are shown. The basic requirements for the quality of the cut surface and a wide range of material properties arising from the characteristics of the energy tool are formulated. The formation of a heat-affected zone, its structure and properties, the formation of macro- and microgeometry of the cut depending on the used working gas are described. The influence of laser cutting parameters on the provision of the required quality and properties of steel is considered.
