Oxy-fuel cutting and oxy-fuel welding can be described asthe processes of using oxygen and fuel gases to either cut or weld metals. There are some striking differences betweenthese two processes. In the first process, a cutting torch is made use of forheating ferrous metal to a temperature of around 980 degree Celsius. An oxygenstream is being trained on a hot metal that combines with iron chemically whichlater flows from the kerfs, or cut in the form of slag of iron oxide. In thesecond process, a welding torch is made use of for welding metals. Torches that burn the inside fuel with air (atmosphere)cannot be termed as oxy-fuel torches. They stand out owing to the use of singletank. This is because oxy-fuel cutting/welding requires oxygen, fuel, and twotanks. Its not possible to melt some of the metals with single-tank torches.Hence, these torches can be used for brazing and soldering, but not forwelding. A metal-cutting torch is better known as hot blue spanner, bluewrench, hot wrench, smoke wrench, and gas-axe. Types of Torches: Thetorch can be defined as the part held and manipulated by the welder to get theweld made. It possesses a valve and connection for oxygen and the same thingsfor fuel gas, a handle to obtain the grip, an integrating chamber (angularlyset) where there occurs a mixing of oxygen and fuel gas, with a tip whereformation of flame takes place. The fuel gases used along with oxygen includepropylene, propane, hydrogen gas, MAPP gas, Liquefied Petroleum Gas (LPG), andthe most widely used is acetylene. Injector Torch: Itcan be defined as an archetypal oxy-fuel torch, also known as an equal-pressuretorch. It carries out the mixing of mere two gases. The injector torch operatesin such a way that high pressure oxygen comes out of the tiny nozzle present inthe torch head, and the fuel gas gets dragged towards it via the venturieffect. Rose-bud Torch:The use of this torch is to carry out the heating of metals forstraightening, bending, etc. It is generally used where a huge area requiresheating. It produces a rose-bud shaped flame at the end, hence the name. Thistorch can carry out the function of heating small areas like rusted bolts andnuts as well. However, here, filler rod wont be used with torch. Cutting Torch:The head of the cutting torch is used for cutting metal. Its identificationdetails are as follows: The inside of the torch consists of a combination ofoxygen and acetylene. It helps in producing flame of a high temperature. Itconsists of 3 pipes going to a nozzle at 90 degree. It also contains anoxygen-blast trigger which blasts away the material during its cutting by theway of providing oxygen. Welding Torch:The welding torch consists of either 1 or 2 pipes running towards thenozzle without oxygen-blast trigger. As the name suggests, it performs thefunction of welding.
