  • Choosing Between Plasma Cutting and Oxy fuel Systems

    Mar 19 Oxy fuel cutting basics 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

  • Oxyfuel Cutting Process and Fuel Gases TWI

    The oxyfuel process is the most widely applied industrial thermal cutting process because it can cut thicknesses from to mm the equipment is low cost and can be used manually or mechanised There are several fuel gas and nozzle design options that can significantly enhance performance in terms of cut quality and cutting speed

  • What Is Oxy Fuel Cutting in Welding An Introduction Tulsa

    May 08 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

  • How does the oxygen cutting process take place

    Since the oxygen cutting process involves directing a high pressure jet of oxygen continuously on to an area of steel that has been previously heated to ignition temperature the basic equipment combines a preheating flame and a pure oxygen source

  • Oxygen Cutting of Metals 5 Processes Metallurgy

    When a workpiece is cut by a thermal cutting process the width of the cut is referred to as KERF which in oxy fuel gas process is a function of oxygen hole size in the nozzle tip flowrate of oxygen and preheating gases speed of cutting and the nature of the material being cut

  • What do you need to know about oxy fuel welding
