Oxy–fuel welding and cutting

Oxy–fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy–fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline or petrol, diesel, biodiesel, kerosene, etc) and oxygen to weld or cut metals. French engineers Edmond Fouché and Charles Picard became the first to develop oxygen-acetylene welding in 1903.
