What is flame-cutting?

Flame cutting, also known as oxy-fuel cutting, is a thermal cutting process used to cut ferrous metals like steel. It uses a flame, typically created by burning a mixture of oxygen and fuel gas (such as acetylene, propane, or natural gas), to heat the metal to its ignition temperature. A high-pressure jet of pure oxygen is then directed at the heated area, causing rapid oxidation (burning) of the metal and blowing away the molten material to create a cut. It's commonly used in fabrication shops, construction sites, and demolition projects to cut steel plates, pipes, and structural shapes.
