Oxy-acetylene welding uses a high-heat, high-temperature flame that is produced by burning a fuel gas (most commonly acetylene) mixed with pure oxygen. Acetylene is stored and transported in cylinders. You might hear this type of welding referred to as “gas Nevertheless, it is a versatile method, using simple and relatively cheap equipment. For the maximum flame temperature in oxygen, the ratio of the volume of oxygen to fuel gas are 1,2 to 1 for acetylene and 4.3 to 1 for propane. A filler metal or “welding rod” is added to the molten pool of the base metals. Oxygen/Acetylene welding, or “Gas Welding”, is a process which relies on combustion of oxygen and acetylene. For use in welding and cutting, the working pressures must be controlled by a regulator, since above 15 psi (100 kPa), if subjected to a shockwave (caused, for example, by a flashback), acetylene decomposes explosively into … 41) Based on data compiled from the U.S. Bureau of Labor Statistics, Employment Projections (2019-2029), www.bls.gov, viewed September 8, 2020.
