Gas-Cutting: Process, Safety & Advantages
Oxy-fuel cutting is widely employed for Industrial thermal cutting as the process can cut thicknesses from 0.5 mm- 250 mm and the equipment is not expensive and can be used mechanized or manually. This process uses an oxidizing flame and a gas-cutting torch to weld or cut. So what do you think an oxy- fuel cutting is? It involves the thermal cutting using oxygen & fuel gas (propane, acetylene, propylene, MAPP or natural gas) to cut materials. This process is also said to be as rapid & controlled rusting. Currently, there are many options in nozzle design & fuel gas types, which enhance the cutting speed & quality. So make sure to buy the gas cutting equipments, Dubai from a reliable supplier in the market.
Oxy- fuel Cutting Process
Different materials have
different ignition temperatures. For steel, this is about 7000C- 9000C.
Initially, the oxygen-fuel mixture is used to preheat the metal to its ignition
temperature (below its melting point). Then a jet of pure O2 is
directed to the preheated section, which leads to an exothermic reaction
between the metal & oxygen to form slag (iron oxide). The jet of O2
removes the slag and pierce through the material to cut the material further
down.
Oxy-fuel process can be employed only
for those metals whose oxides have low melting points than the base metal.
Because when the metal starts to oxidize, it forms a protective crust and
terminates the process. Therefore oxy-fuel process is only used for cutting low
carbon steel and some low alloys which obey the above condition. This method
can be used to cut thicker materials and allows cutting of steeper angles up to
700.
The
Characteristics of a Quality Oxy- fuel cut
1. Clean
smooth surface with near vertical drag lines
2. No under
cuts
3. Cut face
square with respect to top surface
4. Square top
corner with minimum radius
5. Little/no
slag on bottom edge which can be easily removed by scraping
Gas
Cutting Efficiency
Gas cutting efficiency is related to
the speed of the cutting torch and the smoothness of the cut edge. When the
speed is more, the cut edge will be coarser. Make a deal, only with the
reliable welding accessories suppliers in UAE for a smooth and efficient
process.
Gas

There are different types and
varieties of gas cutting equipments for normal and specific functions in the
industry. Most of them are designed and manufactured for the convenience of the
work. Find high quality and certified gas cutting equipments, Dubai for long

Advantages
of Oxy- Fuel Gas Cutting
Gas cutting is popular because of its
advantages than a normal and plasma type of metal cutting processes. So what
are the advantages of oxy- fuel gas cutting process.
1. Oxy- fuel
cutting has high cutting quality with a relatively high cutting speed (+20 %
with acetylene).
2. Low cost
option (low capital cost & low consumable cost) than other cutting
processes.
3. This
process requires no electricity.
4. Oxy- fuel
gas cutting can be done manually or mechanized.
5. The
process can be used to cut thick materials and the equipments are easily
transportable.
Gas-
Cutting safety Precautions
All cutting and welding processes have
to be safely handled. Oxy- fuel cutting/ gas Cutting involves the cutting &
welding of metals using fuel gases. These tasks have risks, so those who work
on cutting industry need to follow safety rules and guidelines to maintain a
safe workplace.
·
Provide fire protection equipments like fire
extinguishers at the workplaces.
·
Use personal protections during gas cutting
against fume inhalation, eye injuries, Bodily injuries or other ergonomic
risks.
·
Follow the safety guidelines for proper
maintenance of gas cylinders and Hoses
·
All cutting equipment should be made grease
and oil free as there is a possible hazard for explosion if O2
interacts with petroleum.
·
Make sure to clean the Gas Cutting Torch tips
before lighting.
·
Use friction lighters to ignite torches.
