|
| A mixture of oxygen and acetylene, used as a fuel in cutting or welding metals.
|
| A group of cutting processes wherein the severing or removing of metals is effected by means of the chemical reaction of oxygen with the base metal at elevated temperatures; in the case of oxidation-resistant metals the reaction is facilitated by the use of a chemical flux or metal powder.

| An oxygen-cutting process wherein the severing of metals is effected by means of the chemical reaction of oxygen with the base metal at elevated temperatures, the necessary temperature being maintained by means of gas flames obtained from the combustion of acetylene with oxygen.
|
| A gas welding process wherein coalescence is produced by heating with a gas flame or flames obtained from the combustion of acetylene with oxygen with or without the application of pressure and with or without the use of filler metal.
|
| An oxygen-cutting process where in the severing of metals is effected by means of the chemical reaction of oxygen with the base metal at elevated temperatures the necessary temperature being maintained by means of an arc between an electrode and the base metal.
