Gas burners use gaseous fuels such as propane, natural gas and acetylene for processes like welding, brazing and soldering. They contain two sources, regulators, and tubes. Different colored pipes designate the purpose of each pipe. Gas burners are essential for metalworking tasks. Welding uses a low-temperature flame, while brazing requires a hotter flame. Soldering requires a filler material and is used for repairs. Gas welding is fueled by acetylene.
A gas burner is a device that uses gaseous fuels to emit a flame. The gases most commonly used by gas burners are propane, natural gas and acetylene. A gas burner can be used for processes such as welding, brazing and soldering.
A typical gas burner contains two sources, one for fuel and one for oxygen. This type of gas burner also generally has two regulators and two tubes. Finally, many gas welders also have a torch that can be applied to brazing and welding jobs.
Regulators on a gas burner control the pressure from the fuel and oxygen tanks. The regulators on a burner are normally operated by the user of the torch, who is able to regulate the flow of oxygen and fuel in the tube. The operator can adjust the regulator to determine the amount of oxygen and fuel that will be admitted through the tube.
The pipes are of different colors, which are meant to designate the purpose of each pipe. Tube colors may vary from country to country. In some countries, an oxygen tube may be blue, while in other countries it may be green. An acetylene pipe is often red. Propane pipes are commonly orange. For safety reasons, it is essential that the oxygen and fuel lines are of different colors so that operators cannot confuse them.
Gas burners are essential for a variety of metalworking tasks. Welding is the process of joining two different pieces of metal together. The metal pieces are joined by a flowing metal that has a low melting point. For this reason it is possible to weld with a gas burner that has a flame with a lower temperature. In many cases, it is possible to weld metals with a Bunsen burner, which uses natural gas.
Brazing, on the other hand, is similar to welding except that the filler metal has a much higher melting temperature. For brazing work it is necessary to use a gas burner which has a much hotter flame. The most commonly used tools for brazing are torch brazers and oven brazers.
Welding with a gas burner is known as gas welding. Like welding and brazing, soldering also requires the use of a filler material, although welding also requires the materials to be joined to be molten. This process is normally used for pipes and tubes. Gas welding is also used for repairs, although it is less commonly incorporated into manufacturing because it requires more manpower than other welding processes. For welding, a gas burner is fueled by acetylene.
