The gas cutting process of metal is a continuous process of preheating, combustion and slag blowing, and its essence is the process of metal burning in pure oxygen, not melting.
Gas cutting uses gas flame to preheat the cut metal to the ignition point, making it burn violently in pure oxygen flow, forming slag and releasing a lot of heat. Under the blowing force of hyperbaric oxygen, the oxide residue is blown away.

Advantages of gas cutting:
1, the speed of cutting steel is faster than the mechanical cutting process with moving blades.
2. For the cutting shape and thickness that are difficult to produce by mechanical cutting method, gas cutting can be realized economically.
3. The equipment cost is lower than that of mechanical tools.
The equipment is portable and can be used in the field.
5. In the process of cutting, the cutting direction can be changed quickly within a small radius.
6. Quickly cut large metal plates on site by moving the cutting machine instead of the metal block.
7. This process can be operated manually or automatically.
