Oxy-fuel cutting; the basics explained HGG 3D Profiling
This slag has a lower melting point than steel, so the oxygen stream can blow the liquid slag out of the cavity without affecting the non-oxidised solid steel. This exothermic reaction is a continuous process and creates a cut as the torch moves. To keep the exothermic reaction working, the cutting torch keeps the steel heated during cutting. Only metals whose oxides

The Cost of Slag Fabricating and Metalworking
If oxygen is used to cut steel, the slag will appear as iron oxide (rust) and a different set of challenges arise. When laser cutting stainless steel after mild steel, or simply if the stainless rests on steel slats, a change in the composition of stainless steel may occur.

Laser Cutting - An Apprentice Engineer's Quick Guide ...
Oxygen and Nitrogen. This has been historically determined by the type of material to be cut. Oxygen is used to cut mild steel and nitrogen is used to cut aluminium and stainless steel. With the onset of Fiber technology, much higher speeds can now be attained with the use of nitrogen in the mild steel cutting process.

Oxy-fuel welding and cutting - Wikipedia
Tests showed that an oxy-gasoline torch can cut steel plate up to 0.5 in (13 mm) thick at the same rate as oxy-acetylene. In plate thicknesses greater than 0.5 in (13 mm) the cutting rate was better than that of oxy-acetylene; at 4.5 in (110 mm) it was three times faster.

Oxy-fuel welding and cutting - Wikipedia
MAPP gas can be used at much higher pressures than acetylene, sometimes up to 40 or 50 psi in high-volume oxy-fuel cutting torches which can cut up to 12-inch-thick (300 mm) steel. Other welding gases that develop comparable temperatures need special procedures for safe shipping and handling. MPS and MAPP are recommended for cutting applications in particular, rather than welding applications.

Kinetics of oxyfuel gas cutting of steels
It was planned that oxyacetylene would be used to cut the steels, and the period of execution of the job would be 6 months, based on the understanding that mild steel (0.16 wt% C) would be used for the steel skeleton. The cost of the project should be N15.23 million. However, the client purchased medium carbon steel (0.33 wt% C). The result was that the rate of job execution was much slower ...

Choosing Between Plasma Cutting and Oxy-fuel Systems
09/02/2021 With oxy-fuel cutting, an oxygen/fuel gas flame preheats the steel to its ignition temperature. A high-powered oxygen jet is then directed at the metal, creating a chemical reaction between the oxygen and the metal to form iron oxide, also known as slag. The high-powered oxygen jet removes the slag from the kerf. When using oxy-fuel torches, cut quality,

Basically, a mixture of oxygen and the fuel gas is used to preheat the metal to its 'ignition' temperature which, for steel, is 700°C - 900°C (bright red heat) but well below its melting point. A jet of pure oxygen is then directed into the preheated area instigating a vigorous exothermic chemical reaction between the oxygen and the metal to form iron oxide or slag. The oxygen jet blows away ...

Cutting mild steel with a laser is balance of how much material is heated up with the laser beam and how much assist gas flows through the cut.

Heating up too large of an area or having too much assist gas flow through the cut will result in the ...

Steel - Removing oxygen Britannica
Steel - Steel - Removing oxygen: As the carbon level is lowered in liquid steel, the level of dissolved oxygen theoretically increases according to the relationship %C × %O = 0.0025. This means that, for instance, a steel with 0.1 percent carbon, at equilibrium, contains about 0.025 percent, or 250 parts per million, dissolved oxygen. The level of dissolved oxygen in liquid steel must be ...

Oxygen - 10 Litre - Gas UK
The steel in contact with the oxygen jet is oxidised, creating metallic slag which is blown from the cut, allowing more steel to react with the oxygen. In plasma and laser-cutting steel, an arc or laser beam is used to heat the steel to its ignition temperature. Oxygen is then used in the same way as with oxygen-cutting to create an exothermic reaction and to blow away any metal oxide or slag ...

For mild steel, the filler wire is solid hence the name solid wire and the gas is argon-carbon dioxide mix which has a component that helps the welding process so for steel welding it is a MAG process as the gas is actively involved in the process (Metal Active Gas). For Aluminium the shielding gas is Argon only and is there to shield only so this is a MIG process and the gas is inert to the ...
