The key industrial use for Oxygen is combustion – Oxygen supports the combustion of a variety of materials such as iron and steel, glass and concrete that wouldn’t usually burn in air. Oxygen mixes with other gases to allow a very hot flame to be produced and can be used to melt metal such as steel, in a room-temperature environment. Oxygen is often used in some shielding gas mixtures due to its ability to help stabilise the arc and reduce surface tension.
