2. Oxy-fuel welding and cutting - Wikipedia

   en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

   The oxy-acetylene (and other oxy-fuel gas mixtures) welding torch remains a mainstay heat source for manual brazing, as well as metal forming, preparation, and localized heat treating. In addition, oxy-fuel cutting is still widely used, both in heavy industry and light industrial and repair operations.

3. Blowtorch - Wikipedia

   en.wikipedia.org/wiki/Blowtorch

   Liquid-fueled torches are pressurized by a piston hand pump, while gas torches are self-pressurized by the fuel evaporation. The term "blowtorch" is commonly misused as a name for any metalworking torch, but properly describes the pressurized liquid fuel torches that predate the common use of pressurized fuel gas cylinders.

4. List of welding processes - Wikipedia

   Air acetylene welding (321) AAW Chemical welding process, not popular Limited Oxyacetylene welding: 311: OAW Combustion of acetylene with oxygen produces high-temperature flame, inexpensive equipment Maintenance, repair Oxygen/Propane welding 312: Gas welding with oxygen/propane flame Oxyhydrogen welding: 313: OHW

5. Acetylene - Wikipedia

   en.wikipedia.org/wiki/Acetylene

   On the other hand, oxy-acetylene welding equipment is quite versatile – not only because the torch is preferred for some sorts of iron or steel welding (as in certain artistic applications), but also because it lends itself easily to brazing, braze-welding, metal heating (for annealing or tempering, bending or forming), the loosening of ...

6. Oxyhydrogen - Wikipedia

   en.wikipedia.org/wiki/Oxyhydrogen

   It is used for cutting and welding [15] metals, glasses, and thermoplastics. [11] Due to competition from arc welding and other oxy-fuel torches such as the acetylene-fueled cutting torch, the oxyhydrogen torch is seldom used today, but it remains the preferred cutting tool in some niche applications.

7. Thermal lance - Wikipedia

   en.wikipedia.org/wiki/Thermal_lance

   Simplified principle and graph of temperature (T) vs distance from the reacting tip (d) of a thermal lance [1] One end of the tube is placed in a holder and oxygen is fed through the tube. The far end of the tube is pre-heated and lit by an oxyacetylene torch.

8. Glossary of firelighting - Wikipedia

   flint spark lighter. Main article: Flint spark lighter. A type of lighter used in many applications to safely light a gaseous fuel to start a flame. It is most commonly used to ignite bunsen burners and oxyacetylene welding torches. A gas wand lighter, typically used for lighting gas stoves A French gasoline lighter in use during World War I ...

9. Shielding gas - Wikipedia

   en.wikipedia.org/wiki/Shielding_gas

   A-25 (25% argon/75% helium) is used for nonferrous base when higher heat input and good weld appearance are needed. A-50 (50% argon/50% helium) is used for nonferrous metals thinner than 0.75 inch for high-speed mechanized welding. A-75 (75% argon/25% helium) is used for mechanized welding of thick aluminium. Reduces weld porosity in copper. [14]
