Oxy-fuel cutting is a combustion process.
An oxygen jet burns the metal in a narrow section to make a
cut and removes the combustion products (slag) from the kerf.
The purity of the cutting oxygen is of key importance for
the cutting speed that can be achieved. High purity oxygen
means high productivity. Before oxy-fuel cutting can begin,
the steel must be preheated to ignition temperature. This is
done by means of an oxygen/fuel gas flame. The choice of
fuel gas influences the cutting process with regard to
quality, preheating times and the thickness of the material
that can be cut with good results. The most critical part of
the cutting equipment is the cutting nozzle. The performance
of a nozzle rises with the increasing exit velocity of the
cutting oxygen jet, which in turn depends on the design of
the nozzle orifice. Working with fuel gases and oxygen can
be risky if the person using the equipment does not have
sufficient knowledge of the equipment and its installation,
handling and care.
Oxy-fuel cutting is used for mild and low-alloy steel in a
material thickness of up to a few meters! The surface
condition has a certain influence on the cut quality, for
example different types of shop primers for temporary
protection against corrosion. Straight cuts, bevel cutting
or weld-edge preparation with several torches simultaneously
are just a few options offered by this versatile tool.
Another is the potential for easy mechanization.
