FACTORS AFFECTING QUALITY IN OXY-FUEL CUTTING

9. Be skeptical of claims made by proprietary fuel gas suppliers for hotter flame temperature, faster cutting speed or better cut quality. Cutting speed on a thin plate (less than or equal to 1/2”) is controlled by preheat intensity (flame temperature) and in heavier plate cutting by oxygen stream shape and quality, not the fuel type.

Oxy-fuel cutting; the basics explained | HGG 3D Profiling

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.

Gas-Cutting: Process, Techniques and Advantages | Welding

The process consists of preheating the metal to be cut to its ignition (oxidation) temperature, i.e., above 870°C in case of steel. The preheating is done by oxy-acetylene gas flame, which is supplied from surrounding openings of the cutting torch. When this temperature is attained, a jet of high pressure oxygen from a central opening of the cutting torch is directed on the red hot metal.
