Oxy-fuel cutting

Oxy-fuel technology

In case of mild steel of higher thicknesses, oxy-fuel cutting is the qualitatively optimal cutting procedure. Although plasma and laser cutting has gained in popularity, oxy-fuel cutting remains a highly economic cutting procedure, achieving good cut quality. In particular in case of material thicknesses of up to 1200 mm, oxy-fuel cutting remains the method of choice.

Metal cutting technologies: oxy-fuel cutting

What is oxy-fuel cutting ?

A flame of propane, acetylene or high fuel-value natural gas from a torch is used to pre-heat the to-be-cut material quickly to its ignition temperature (ca. 1050 to 1526 degrees Celsius. Subsequently, a gas jet of minimum 99,5% oxygen is blown onto the heated material, so the pre-heated material starts to burn. The torch is dragged further, and where the burnt material is missing, a narrow kerf occurs.

As this burning of material (oxidation) is an exothermic process, hence releasing energy and thereby feeding itself, the procedure is very energy-saving. The torch is only required to maintain the ignition temperature along the kerf.
