Abstract
Gas laser processing of metal alloys is considered on the example of gas laser cutting with different power, speed, auxiliary gas pressure and focal length. As a result of the comprehensive
studies carried out, it was found that the use of gas laser cutting in the manufacture of parts from metal alloys of the iron –carbon system opens up the possibility of combining in one operation and obtaining and hardening the part without the use of additional thermal and chemicalthermal treatment. Adequate mathematical nonlinear regression models have been developed
for the extent of the gas-laser thermal influence zone (L); orthogonality of the cutting surface (a); surface roughness of the gas-laser cut (Rz), which link the quality indicators of the gaslaser
cutting surface with the parameters of laser processing, the carbon content in steel and the thickness of the steel sheet.
