  • Which is the best fuel gas for oxyfuel cutting?

    Mar 09, 2020 · Oxy acetylene cutting has pretty much become synonymous with oxyfuel cutting. The reason is that this is the most common fuel used in the process. The main reason for that is the temperature it can achieve – around 3200° C. Such a high temperature makes faster piercing and …

  • CNC Oxyfuel Cutting Machines | Oxy-fuel Cutting Systems ...

    Maybe you’ve heard oxy-fuel cutting described as “burning”, “torch cutting”, or “flame cutting”. Each of these names contains an element of truth in describing the process. An oxy-fuel cutting torch is used, it has a flame, and the steel is “burned” as it cuts.

  • Oxyfuel cutting | Linde Gas

    Apart from using hacksaw, power saw, chisels, etc. for metal cutting operation, gas or oxygen cutting is extensively used now-a-days in industry. Oxy-fuel cutting (OFC) is similar to ox fuel …

  • How to improve oxy-fuel cut quality - ESAB Welding & Cutting

    Oxy-fuel cutting: the basics Before cutting, the cutting torch has to pre-heat the steel to ignition temperature at the starting point. At this temperature of around 960°C (depending on type of alloy), the steel has lost protective properties against oxygen and is still solid. Pure oxygen is then directed through the nozzle at the heated area.

    Basics Of Oxy-fuel cutting Q. What is Oxy-Fuel Cutting? A. Oxy-fuel cutting is a chemical reaction between pure oxygen and steel to form iron oxide. It can be described as rapid, controlled rusting. Q. How does it work? A. Preheat flames are used to raise the surface or edge of the steel to approximately 1800°F (bright red color).

  • Setup and Shutdown Procedure for Oxy- fuel Cutting Torch

    Feb 10, 2021 · Completely open the oxygen valve on your torch handle, and open the preheat oxygen valve with a cutting attachment. Hold the cutting lever open for 5 seconds, then shut the oxygen valves and repeat for the fuel gas side.

  • (PDF) Oxy-fuel welding and cutting | sewalem gezie - Academia.edu

    Oxy-fuel combustion is the process of burning a fuel using pure oxygen, or a mixture of oxygen and fuel gas, instead of air. Since the nitrogen component of air is not heated, fuel consumption is reduced, and higher flame temperatures are possible.

  • Oxyfuel Gas Cutting | Metalworking: Sheet Forming ...

    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) and oxygen to weld or cut metals. French engineers Edmond Fouché and Charles Picard became the first to develop oxygen- acetylene welding in 1903.

    Jun 30, 2015 · Health Hazards of Oxy-Acetylene Cutting & Welding-June 2015. Oxy-acetylene cutting – also known as gas cutting or oxy-fuel cutting – is often considered less hazardous than traditional welding. Accordingly, the health hazards are often ignored. However, most or all of the hazards of welding may still exist. In gas cutting, a torch is used ...

  • OxyFuel Cutting with MAPP Gas : Maine Welding Company

    Mar 19, 2021 · With oxy-fuel cutting, an oxygen/fuel gas flame preheats the steel to its ignition temperature. A high-powered oxygen jet is then directed at the metal, creating a chemical reaction between the oxygen and the metal to form iron oxide, also known as slag. The high-powered oxygen jet removes the slag from the kerf.

  • History + Timeline of Oxygen-Acetylene Metal Cutting ...

    Oxyfuel cutting (OFC), also called flame cutting or burning, is a process that uses the flame and oxygen from a cutting torch to cut ferrous metals. The flame is produced by burning a fuel gas mixed …

  • Cutting Torch Oxy fuel Equipment Inspection

    Typical edge conditions resulting from oxyfuel gas cutting operations: (1) A good cut in 1″ (25.4mm) plate. The edge is square, and the drag lines are essentially vertical and not too pronounced. (2) The preheat flames were too small for this cut, and the cutting …

  • CNC Oxyfuel Cutting Machines | Oxy-fuel Cutting Systems ...

    Gas welding, sometimes also known as oxy-fuel welding, is another technique to weld. This technique is slow and easier to control when compared to arc welding. The metal pieces are combined by a heat source produced as a result of the combustion of fuel gas, such as acetylene, methylacetylene (MAPP), or hydrogen gas.

  • Setup and Shutdown Procedure for Oxy- fuel Cutting Torch

    An oxy-fuel cutting torch is used, it has a flame, and the steel is “burned” as it cuts. The actual chemical process that takes place is sometimes described as “rapid rusting” of the steel. Whether you think of it as burning or rusting, the result is similar – the steel is rapidly oxidized in a chemical reaction that generates heat.

  • 1910.253 - Oxygen-fuel gas welding and cutting ...

    Oxy-Fuel gas cutting is functional for use with low carbon and low alloy steels, with a carbon content generally restricted to 1/10 to 3/10 of 1%. The various alloy elements found in steel affect the ability of the oxygen to cut the metal. Elements such as manganese, silicon, phosphorus, and sulfur have very little effect in normally found levels.
