Oxygen Cutting of Metals: 5 Processes | Metallurgy
Oxygen Cutting of Metals: 5 Processes | Metallurgy

Oxy-fuel gas process involves preheating a small zone, wherefrom the cut is to be started, to the kindling temperature of the material. Compressed oxygen is then made to impinge upon the hot metal resulting in very high rate of oxidation which is often accompanied by evolution of heat due to exother­mic nature of the reaction.

How to cut steel - Thermal cutting/Oxy-fuel cutting process

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.

1/5/2020, · The first step in the oxyfuel cutting procedure requires a, mixture of oxygen and gas, to, help preheat the metal or steel in, its ignition form. The preheating metal process is also known as the, oxidation process., The temperature in order to preheat the metal effectively should be around 700 °C to 900 °C, preferably well below its melting point.

Cutting with an Oxy/Mapp torch? - Instructables

I mostly use a oxy/map torch for welding, but for cutting you ignite the mapp gas and then turn the oxygen until you get a small blue flame about 5/16in. long.Differnt metals have a lower melting points and the thickness of the metal may also affect how long the blue flame should be so just adjust the oxygen until the metal begins to melt.

The oxy-fuel cutting process is capable of cutting steel whose composition is less than .3% carbon. Mild steel is comprised of 98% iron, 1% manganese, carbon up to .3% and various other elements in small amounts. Oxy-fuel cutting cannot cut non-ferrous metals such as aluminum, stainless, brass or copper.

Oxy-fuel cutting; the basics explained | HGG 3D Profiling
Oxy-fuel cutting; the basics explained | HGG 3D Profiling

Oxy-fuel cutting: the basics Before cutting, the cutting torch has to pre-heat the steel to ignition temperature at the starting point. At this temperature of around 960°C (depending on type of alloy), the steel has lost protective properties against oxygen and is still solid. Pure oxygen is then directed through the nozzle at the heated area.

Slightly open the valve for acetylene on the cutting torch. Make sure that it does not exceed a half-turn. Use a flint striker or spark lighter to ignite the acetylene gas flowing out of the torch’s nozzle. Soot or black smoke may come out once it is lit up, which is considered normal.

Oxy-fuel cutting is a time consuming process, especially cutting thick walled materials. The shortest distance through the material is a cut perpendicular to the wall. In case of a beveled cut (an angled cut for weld preparation) the cutting torch will be at an angle and the heat transfer to the material will be less than that of a perpendicular cut and the cut length will be greater.

But as acetylene has a limited outlet pressure, ,MAPP, is the only gas other than hydrogen that can be used for ,cutting, in deep water. Propylene It gives off a high heat release in the outer cone (72,000 kJ/m3) but, like propane, it has the disadvantage of having a high stoichiometric oxygen requirement (oxygen to fuel gas ratio of approximately 3.7 to 1 by volume).
