[4] See more Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline or petrol, diesel, bio diesel, See more The apparatus used in gas welding consists basically of an oxygen source and a fuel gas source (usually contained in cylinders), … See more Oxygen is not the fuel. It is the oxidizing agent, which chemically combines with the fuel to produce the heat for welding. This is called 'oxidation', but the more specific and more commonly used term in this context is 'combustion'. In the case of hydrogen, the … See more Oxyacetylene welding/cutting is not difficult, but there are a good number of subtle safety points that should be learned such as: See more Oxy-fuel torches are or have been used for: • Heating metal: in automotive and other industries for the … See more Oxy-fuel processes may use a variety of fuel gases (or combustible liquids), the most common being acetylene. Other gases that may be used are propylene, liquified petroleum gas (LPG), propane, natural gas, hydrogen, and MAPP gas. Liquid fuel cutting … See more The welder can adjust the oxy-acetylene flame to be carburizing (aka reducing), neutral, or oxidizing. Adjustment is made by adding more or less oxygen to the acetylene flame. The neutral flame is the flame most generally used when welding or cutting. The … See more WebThe maximum flame temperature for acetylene (in oxygen) is approximately 3,160°C compared with a maximum temperature of 2,828°C with propane.

Oxyfuel Cutting - Process and Fuel Gases - TWI

WebMay 8, 2024 · Oxy-fuel cutting is one of the most commonly used processes in welding, and for good reason. The initial cost of purchasing the equipment is less expensive than for other processes like plasma cutting. The equipment can be used for a wide range of processes, not just cutting. It is quick and easy to set up. Welders can employ oxy-fuel … WebA typical value of temperature obtained in a plasma jet torch is on the order of 28000 °C (50000 °F), compared to about 5500 °C (10000 °F) in ordinary electric welding arc. All welding arcs are (partially ionized) plasmas, but the one in plasma arc welding is a constricted arc plasma. WebFeb 4, 2024 · • Workpiece temperature of 1200°C is needed to sustain the cutting. Low carbon steel from 5 to 75 mm can be cut. • Cast iron can’t be cut to a smooth finish as it starts melting and flowing before it can be oxidized. Similarly, other nonferrous metals behave in a similar fashion. Oxy-acetylene cutting procedure how to verify contractor license in ca
