What kind of cutting process applies oxy-fuel?
Oxy-fuel cutting is a thermal cutting process that uses oxygen and fuel gas (such as acetylene, propane, MAPP, propylene and natural gas) to cut through materials.
What is the process of oxy acetylene cutting?
A heating flame is directed on the metal to be cut to raise it to bright red heat. Then a stream of high-pressure oxygen is directed on to the hot metal. The Steel and Iron is immediately oxidised to magnetic oxide of iron (Fe3O4).
What is flame cutting process?
Flame cutting is oxygen cutting in which the appropriate part of the material to be cut is raised to ignition temperature by an oxy-fuel gas flame (definition from BS 499:Part 1:1991 Section 7 No. 72 002). Also known as oxy-fuel cutting, the process is used for separating and shaping steel components.
What are advantages of oxy-fuel cutting?
Frequently Asked Questions
| Process | Advantages | Disadvantages |
|---|---|---|
| Oxy-fuel | Can be used to cut thick sections | |
| All positions | ||
| Plasma | Wide range of materials including stainless steel and aluminium | Typically limited to 50mm (air-plasma) plate |
| Narrow HAZ | Noise when cutting thick sections |
What is the difference between plasma cutting and oxy-fuel cutting?
Plasma cuts any electrically-conductive metal (steel, aluminum, copper, stainless steel, etc.) from very thin (<3/8 in.) up to 2 inches. Oxy/fuel cuts ferrous (iron-containing) steels up to 24 in.
What is the formula of Oxy acetylene?
As an alkyne, acetylene is unsaturated because its two carbon atoms are bonded together in a triple bond….Acetylene.
| Names | |
|---|---|
| Chemical formula | C2H2 |
| Molar mass | 26.038 g·mol−1 |
| Appearance | Colorless gas |
| Odor | Odorless |
How does oxy acetylene cut metal?
Oxy Fuel Cutting Definition Flames via an oxy fuel torch are used to increase the temperature of the metal and then pure oxygen, in a precise, high-pressure stream, is directed at the heated surface at a constant speed. A cut is formed as the affected metal becomes rapidly oxidized and is blown away.
What are the advantages of oxy-fuel cutting?
What are some of the benefits of the oxy-fuel cutting process?
Oxy-fuel cutting basics and benefits of the process Oxy-fuel torches have a leg up when it comes to cutting thicker metals, and they can offer greater portability in certain situations. Oxy-fuel torches also offer versatility, as they are capable of cutting, welding, brazing, soldering, heating and gouging.
How does the oxy acetylene cutting torch work?
Cutting torch When cutting, the metal is first heated by the flame until it is cherry red. Once this temperature is attained, oxygen is supplied to the heated parts by pressing the oxygen-blast trigger. This oxygen reacts with the metal, producing more heat and forming an oxide which is then blasted out of the cut.
What is oxyfuel cutting?
Oxyfuel cutting – process and fuel gases Oxy-fuel cutting is a thermal cutting process that uses oxygen and fuel gas (such as acetylene, propane, MAPP, propylene and natural gas) to cut through materials.
What gases are used in oxy-fuel cutting?
Other gases utilized include natural gas, propane, hydrogen, propylene, liquified petroleum gas (LPG), and combinations of these gases. Oxy-fuel cutting begins by using a torch to heat a metal to its kindling temperature. This is the lowest temperature at which the metal in question will spontaneously ignite.
What metals can not be cut with oxy fuel?
Oxy-fuel cutting cannot cut non-ferrous metals such as aluminum, stainless, brass or copper. Elements such as chromium, nickel, molybdenum inhibit the ability to cut steel with the oxy-fuel process. Manganese, silicon, phosphorus, and sulfur in normal amounts have little effect on the cutting process.
How can I increase the cutting speed of my oxy fuel torch?
Using an extra oxy fuel torch (pre heat torch) can be installed perpendicular to the material and running in front of the cutting torch can improve the cutting speed significantly (100% at 70 degrees cutting angle and 50% at 45 degrees cutting angle).
