Abstract

A method of laser-beam cutting stainless steel, other high-alloy steel materials, and aluminium or aluminium alloys while using nitrogen as a cutting gas. According to the method, there is used nitrogen which contains oxygen in a small amount corresponding to 0.1-10 volume-%. The oxygen content is preferably 0.5-5.0 volume-%. The invention also relates to a gas composition for use when carrying out the method.
