Besides forge welding, Oxy-fuel is one of the oldest welding processes. Oxy fuel cutting & welding is a machine that uses oxygen as the primary fuel for cutting and welding of solid materials. It is also known as gas welding technique, which uses a torch to weld the metals. Welding is done when the two set of metals are kept and treated under extreme heat which gives a molten metal being shared amidst the two pieces into one. It also involves various other metals which is known as filler while it plays a major role when welding the objects. The oxy fuel cutting machine emits iron oxide flames which could easily heat the object with the high velocity temperature.
You all might have a question whether oxy fuel cutting could be used to cut any kind of metals, isn’t?
This type of cutting machine could not be used for cutting all type of metals. This could be used to cut metals under lower melting point. If this method is used to cut heavy metals that exceeds to highest melting point will result in crust and thereby the object results in damage.
This method could be used only by the professional engineers or trained people who have enough experience in cutting the objects. The trained professionals and engineers will know the fundamental procedures involved in cutting the object and they perform the job efficiently and quickly as possible.
Oxy fuel cutting involves the use of some gas that could preheat the flame and make the cutting process efficient. Acetylene gas is the basic and common type of gas used in the oxy fuel cutting process. Besides this, the propane, methyl acetylene, hydrogen, propylene, natural gas and liquefied petroleum gas are also used.
The oxy fuel cutting involves the cutting torch to cut and weld the objects. This type of torch is quite different when compared to the other welding torch. It includes 3 different pipes which could run with the torch. It contains a triggering operation which would be pulled and applies the oxygen force over the surface. The oxygen gas blends the chemicals for producing heat. This type of procedure is also called as oxidation and it is sometimes referred to combustion also.
People who are involved in the oxy fuel cutting must keep a few factors in mind to ensure that cutting is done efficiently:
Make sure that the supply of oxygen is perfect and streamlined. High flow of oxygen is not recommended instead a streamlined and steady flow of oxygen will result in perfect cutting of objects.
Do not reduce the level of oxygen flow, because it would jag and slow the cutting process. As a result, the output and end result will not be perfect like you expected.
Never increase the level of huge oxygen supply, because the gas goes waste and moreover it results in wide and concave cut.
Remember, the use of oxy fuel cutting will never give you precise and clean cutting result. Particularly if the metal remains very hard or rigid, then it is undoubtedly hard to score the nearest to perfection result like other machines do. However when electricity is not easily accessible or when the area itself is hard to access, these Oxy Machines are easier to transport.
