Oxyacetylene flame cutting

Autogenous cutting is a flame cutting process. In flame cutting, a fuel gas, usually acetylene, is burned with high-purity oxygen.

In flame cutting, the material is removed by reaction with the oxygen applied to the heated metal. Autogenous flame cutting is mainly used for cutting low and medium carbon steels. Non-ferrous metals, high carbon steels and stainless steels are more difficult to cut as they are more resistant to oxidation.
