CO2 Laser Cutting Of Non-Ferrous Metals

This paper describes the mechanisms by which non-ferrous metals can be cut by CO2 laser. Materials dealt with include titanium, alumimium, copper and nickel alloys. The differences between inert gas and oxygen assisted laser cutting are explained and examples of cut qualities and speeds are given. Cutting efficiencies are related to the physical properties of the various alloy systems with particular emphasis placed upon reflectivity and conductivity. Specialised techniques developed for non-ferrous metal cutting are described and commercial applications of the process are discussed.
