gas cutting

Gas cutting involves the fuel gases and oxygen to cut the parent metal to be used for jobs.
The gases like acetylene or hydrogen is used for heat generation.
Acetylene reacts with oxygen and it is exothermic reaction

                                          2C2H2 + 2O2 → 4CO + 2H2+energy

Again the carbon mono-oxide reacts with oxygen and releases energy

                                 4CO+2H2 +3O2 → 4CO2 +2H2O+energy

It is economical and can be used for bevel and groove welding.
