This is the principal and easiest method for cutting steel, it simply burns a slot into the material using pure oxygen.
Flame cutting technology is still the principal process for cutting metal plate for most metal processors.
This process uses gases, propane, and oxygen to produce a controlled flame.Applications are limited to carbon and low alloys steel.
These materials can be cut economically, and set up is simple and quick.
This process is the best choice for end-users requiring inexpensive cutting of carbon steel and most alloys.
But, Flame cutting creates a heat affected zone (HAZ) around the cut that may need to be removed by additional machining.
Advantage of Flame Cutting
Flame cutting employs multiple-torch capability , this means that the process is ideal for high production runs.
Flame cutting is the best choice for metal cutting where the cut material is to be followed by machining activities since it often requires secondary operations to produce a satisfactory finished product.
Flame cutting consists of a number of cutting processes used to cut metals by means of the chemical reaction of oxygen with the base metal at elevated temperatures.
The required temperature is maintained by via a flame obtained from the combustion of a specified fuel gas mixed with pure oxygen.
A jet of pure oxygen is directed into the preheated area instigating a chemical reaction between the oxygen and the metal to form iron oxide or slag, which the oxygen jet blows away.
