Oxygen is used in oxyacetylene welding burning acetylene with to produce a very hot flame. It is most commonly used for Bunsen burners and oxyacetylene welding torches. The most common gas welding process is oxyfuel welding, also known as oxyacetylene welding. Some modern blacksmiths may also employ an oxyacetylene or similar blowtorch for more localized heating. Straightening of warped steel weldments is done with an oxyacetylene torch. A three-man team using oxyacetylene torches ignited some oil, causing an explosion. The stern was cut from the once intact hull by oxyacetylene torches. A major new market emerged around 1903, with the development of the oxyacetylene welding process. The far end of the tube is pre-heated and lit by an oxyacetylene torch. This would prevent both standard explosives and oxyacetylene cutters from penetrating the vault. In most cases heating will be done by use of the oxyacetylene flame. For steel materials, oxyacetylene cutting is the most common form of preparation. The second album "Cyberia" (1994) spawned the hit single "Oxyacetylene", generally considered Cubanate's creative peak. Oxyacetylene is the hottest burning common fuel gas. Oxyacetylene welding may also be used in areas where electricity is not readily accessible.
