1. gas welding
2. Oxy-fuel welding and cuttingOxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the U.S. ) and oxy-fuel cutting are processes that use fuel gases and oxygen to weld and cut metals, respectively. French engineers Edmond Fouché and Charles Picard became the first to develop oxygen-acetylene welding in 1903. 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 room environment.
