Oxy-Fuel Welding and Cutting

Return to welding history

Oxy-fuel welding is a welding process commonly called oxy-acetylene welding, since acetylene is the predominant choice for a fuel, or often simply gas welding. A virtually identical procedure, with a different type of gas torch, is used for cutting metal and called oxy-fuel cutting. In gas welding and cutting, the heat energy and high temperature needed to melt the metal is obtained by the combustion of a fuel gas with oxygen in a torch. This sort of torch is often called a blowtorch.
