The technique of oxyacetylene welding, also known as gas welding, depends on the combustion of oxygen and acetylene. A relatively hot flame with a temperature of about 3,200 C is produced when the ingredients are combined in the right quantities in a hand-held torch or blowpipe. By altering the volume of oxygen to acetylene, the oxyacetylene flame's chemical reaction can be controlled.

The most common setting for welding is the neutral flame, which contains an equal amount of acetylene and oxygen. The only gas mixture that has enough heat to weld steel is an oxygen and acetylene mixture. However, alternative gases can be used to combine non-ferrous metals with lower melting points, such as propane, hydrogen, and coal gas.
