Pre-heating - Messer Cutting Systems With our diverse pre-heating torches, heat can be applied targeted to the areas of the components you require The process is especially suitable for pre-heating and post-heating when welding and cutting, for shrinking processes and the pre-heating of casting moulds and ingot moulds
Oxy-Fuel Cutting Equipment - Weld Guru The cutting torch (see figure 5-12 below), like the welding torch, has a tube for oxygen and one for acetylene In addition, there is a tube for high pressure oxygen, along with a cutting tip or nozzle
Theory of Oxy-Fuel Gas Cutting - Harris Products Group A cutting torch diverts the oxygen and mixes part of it with the fuel gas to create the preheat flame, forming the ring of flame around the cutting tip This preheat flame will reach a temperature of 4400°F to 6000°F, depending on the fuel gas used as well as the ratio of oxygen to fuel gas
Oxy-Fuel Torch Cutting – Acetylene vs Propane The choice between acetylene and propane for oxy-fuel cutting depends on specific operational requirements, including material type, thickness, desired cut quality, and cost considerations
Oxyfuel Cutting | Linde formerly Praxair The torch used in the cutting process produces the preheating flame by mixing fuel gas with oxygen in the correct proportions to support combustion It also provides a concentrated stream of pure oxygen to the base plate This oxygen oxidizes the hot metal and removes it from the joint area
The essential guide to oxy-fuel cutting | In the spotlight article . . . In oxy-fuel cutting, metal is heated, then a high-pressure jet of pure oxygen is added to create a clean cut In this guide we provide more detail on how cutting works, the equipment you’ll need, and how different fuel gases affect the cutting process
Oxy-Fuel Torch Tip Nozzle Preheat Design - ESAB India Unlike the cutting Oxygen bore design, the preheat design does not change with plate thickness Below is a photograph showing the three preheat designs, for the four fuel gases, natural gas, and propane using the same design
