Effect of cutting speed by laser on Thickness of heat affected zone of mild steel S235

Abstract

The presented article describes the technology of laser cutting. Article describes the characteristics of the laser beam by CO2 laser, the factors on the process of laser cutting, assistance gas and interaction cut material properties and stability of the cutting process. There is characterized conventionally used material - mild steel S235 and cutting method of laser, including the impact of technological parameters of laser cutting on integrity of cutting edge. Experimental samples of material S235 are cut with different technological parameters of laser cutting and is monitoring heat affected zone in each samples. Heat affected zone is displayed graphically and evaluated the impact of change of cutting speed to thickness of heat affected zone.
