ABSTRACT:
In autogenous cutting oxygen in liquid form is put under high pressure and flows to the cutting site through a liquid jet cutting nozzle. An increase in the cutting speed and in the cutting quality level is achieved in that the super-cooled liquid oxygen jet emerging from the nozzle has a temperature that is below the boiling temperature of the oxygen at ambient pressure.
