Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding and oxy-fuel cutting are processes that use fuel gases and oxygen to weld and cut metals, respectively. It uses Pure Oxygen, instead of air (20% oxygen/ 80% nitrogen), is used to increase the flame temperature to allow localized melting of the workpiece material (e.g. steel) in a worksop. A common air flame burns at about 2,000°C, the oxygen flame burns at about 2,500°C and an acetylene/oxygen flame burns about 3,500°C.

Oxy-fuel is one of the oldest welding processes. Still is used in a workshop, in recent years it has been less widely utilized in industrial applications as other specifically devised technologies have been aopted. it is still widely used for welding pipes and tubes, as well as repair work. It is also frequently well-suited, and favoured, for fabricating some types of metal-based artwork.
