Gas cutting of metal with propane

Gas cutting of metal with propane It is the most effective and popular type of cutting, as it doesn't require a special room or grounding cable, and it remains portable when moved. Propane gas is used to heat the metal, while oxygen separates the metal. The heating temperature at gas cutting of metal with propane 1000 — 1200⁰This allows the jet to ignite when oxygen and metal combine. When cutting with propane, the weld remains relatively clean compared to electric metal cutting. The flux is ejected by the preheating flame during cutting, but can also burn through the metal. It's important to keep in mind that gas cutting of metal with propane not used when cutting metal with a melting point below 600⁰ C, otherwise the top layer of metal will be removed.

Cutting metal with a gas cutter Modern cutting occurs at a pressure of 12 atmospheres. The torch handle has two tubes built into it, with three of them leading to the nozzle. Two of these tubes are supplied with propane, and the third with oxygen. The oxygen consumption varies depending on the torch model. Cutting metal with a gas cutter P1 - 01 uses 10m per hour of work³. oxygen and 1m³ Propane. The P2-01 torch model consumes much more gas. This torch can cut low- and medium-carbon steels and cast iron. High-carbon steels do not allow oxygen to penetrate deep enough to burn through the metal. Non-ferrous metals such as aluminum, copper, and their alloys are also not suitable for gas cutting.

Cutting metal with a gas cutter It is successfully used when cutting thick metal, cutting out thick discs, burning a blind hole of 20-50 mm, the work is carried out much faster than with other cutting methods, and propane is also cheaper than gasoline and other flammable gases.
