Some Studies of the Plasma Cutting of Aluminium Plates

Abstract

Plasma arc cutting of metals is of recent origin and is widely employed in the cutting of stainless steels, special steels, non-ferrous metals and their alloys, thick sections of steel and even C.I. In oxygen cutting, the metal burns reacting with oxygen. Therefore, the speed of cutting of carbon steels for which it is widely used is limited by the speed of the chemical reaction of oxygen with iron and the speed with which the molten metal is blown away from the reaction zone.
