FIELD : processes and equipment for gas-laser cutting of titanium and its alloys, possibly in different branches of power engineering and machine engineering.SUBSTANCE : method is realized due to using technological gas being mixture of argon and oxygen and containing 15 -25% of oxygen. In order to cut metal of predetermined thickness, oxygen content in technological gas is determined depending upon cutting speed and quality of metal surface according to technological demands for cutting quality at maximally admissible cutting speed.EFFECT : improved quality of cutting as oxygen content of technological gas in preset range completely prevents occurring of type-metal or makes it rare and small.1 dwg, 1 ex
