The flame cutting often also called oxy acetylene cutting, the cut thickness range from 6mm to 200mm. Usually less than 20mm thickness steel plate will be using the laser, water or plasma cutting. The main reason is the flame cutting will lead to a bigger thermal deformation area. But it's the most cost-effective method for cut the more than 20mm thickness carbon steel plate. The cut quality depends on the Oxygen purity and the operator's ability and experience. The flame cutting is widely used in the manufacturing of steel structures.

The plasma cutting collocation with different gases can be cut a variety of flame cutting difficult to cut metals. Especially for non-ferrous metals cut effect better, like the stainless steel, aluminum, copper, titanium, nickel. Usually the cut thickness less than 30mm. Compared with the flame cutting, the plasma cutting has the advantages of the high cut speed (the cut speed is 3-4 multiples of flame cut), cut surface smooth, small heat distortion and less heat affected area. The plasma cutting is widely used in automobiles, locomotives, pressure vessels, chemical machinery, construction machinery, steel structure, ship industry and more. But the laser cutting is gradually replacing the plasma cutting due to the equipment costs and the using cost reduction.

The difference between flame cutting (oxy acetylene cutting) and plasma cutting:
1. Different cut methods: the flame cutting is use of the gas burning to achieve high temperature processing. The plasma cutting is use of the high temperature plasma arc heat to achieve processing.
2. Use different gas: the flame cutting work requires gas and oxygen, and it can be used in three kinds of gas: coal gas, propane, acetylene. The gas used in the plasma cutting process includes argon, hydrogen, nitrogen, oxygen, air, water vapor and other mixed gases.
3. Cut thickness: the thickness of the flame cutting from 6mm to 200mm, and the cut thickness can be reach more than 300mm after the equipment is modified. The thickness of the plasma cutting is determined to the specification of power supply.
4. Different cutting applications: the flame cutting is usually used for the processing the materials of more than 20mm thickness carbon steel. The plasma cutting are mainly used for processing the less than 20mm thickness metals, such as: steel, stainless steel, aluminum, copper, titanium, nickel.
5. Cut speed: if cut for 20mm thickness steel plate with the flame cutting speed: 450mm/min and the plasma cutting speed: 1500mm/min.
