Abstract
The workpiece is obtained by cutting a metal product by oxygen cutting. An oxygen cutting jet is sent onto a preheated cutting zone of the product. A peripheral sleeve of additional gas is formed around the oxygen cutting jet so as to send, into the cutting zone, a coaxial double jet constituted by the oxygen jet surrounded by the sleeve of gas at a pressure of less than 1 bar. The flow rate and the pressure of the cutting oxygen and of the additional gas are regulated separately. The invention also relates to an oxygen-cutting device for implementing the method and to the metal part obtained.
