Gas Cutting Process

Gas Cutting Process Points : Gas Cutting Process, Principle of Gas Cutting Process The principle of this gas cutting process is the fast oxidation of the metal in a small part. Metal is heated to a bright red color with a discharge of high pressure oxygen is forced beside it. The oxygen blast mixes by the hot metal to burn it to an oxide (a mixture of oxygen by an additional element) in this case generate slag. The ensuing reactions produce a strong heat, which is responsible for cutting. High temperature oxide heats the metal in its path to ignition or kindling point, among 1400°C. The area affect combines by the cutting oxygen and also burns to an oxide. This is blow away on the opposite side of metal. The process causes the metal to divide, leaving a narrow slot or kerfs. While heated to a high temperature, almost all metals will readily combine by oxygen. Several metals though, cannot be effectively cut by this process because their oxides contain a higher melting point than the metal being cut. These cause the oxides to mix by the metal instead of separating it stainless steel and cast iron arc of this kind as well as the nonferrous metals such as aluminum, magnesium with brass.
