Frequently asked questions about oxyfuel cutting
Pure oxygen, introduced in a fine, high-pressure stream, is then directed toward that heated section of steel. As the steel is oxidized and the oxygen stream helps to blow away the resulting slag, the "cut" occurs. In mechanized systems, the preheat and oxygen stream is then moved at a constant speed to finish the cutting process.
Fuel Gases Used for Oxyfuel Cutting
And here lies the reason why flame cutting is not suitable for cutting stainless steel. Lastly, the high-pressure oxygen jet blows away the slag, or iron oxide, cutting the metal in the process. Oxyfuel Cutting Gases. So the name of the process is pretty self-explanatory. The cutting method uses both oxygen and a cutting gas.
