OXY-FUEL FLAME CUTTING

OXY-FUEL FLAME CUTTING

In oxyfuel cutting, oxygen is used as the cutting gas. Cutting is initiated by heating the edge of the steel to the ignition temperature, and then torch blows extra oxygen at higher pressures into the workpiece. The chemical reaction releases large amounts of energy causing the metal to burn and blowing the resulting molten oxide through to the other side. The oxygen chemically combines with the iron in the ferrous material to instantly oxidize the iron into molten iron oxide, producing the cut. Initiating a cut in the middle of a workpiece is known as piercing.

A. WHY OXY-FUELOxyfuel cutting - arguably one of the most time-honored and trusted methods of cutting steel - is the tool for you if you’ll be cutting thicker metals. One limitation to keep in mind, however, is that oxyfuel cannot cut stainless steel and aluminum. Oxyfuel is particularly effective on ferrous (iron-containing) metals. Oxyfuel can efficiently cut even the thickest metals.

B. CUTTING PROCESSOxyfuel cutting is a combustion process using oxygen/fuel gas flame. The heating flame brings the material up to its ignition temperature. Then a jet of oxygen at least 99.5% pure is blown onto the heated spot. The oxygen jet oxidizes the metal then the torch is moved and a narrow cutting kerf is created, removing the slag from the kerf. The quality of the cut depends on the surface condition of the material, cut-velocity, and thickness.

All low alloy steel with a material thickness up to several inches can be cut with this process. Despite the increasing significance of the other cutting processes such as Plasma and Laser cutting, Oxyfuel flame cutting is still a very economical process. For heavy material thicknesses up to 900mm there is no alternative to Oxyfuel flame cutting.

Oxyfuel cutting ensures reliable hole-piercing, high cut quality which the production of components to their finished sizes without the need for further processing. For weld seam preparations V, Y, and K cuts can be produced.

C. ADVANTAGES AND APPLICATIONS■ Good cut quality■ Smooth, vertical planes of cut■ Metallurgical perfect surfaces (oxidized)■ Carbonizing and hardening within the area of the heat affected zone■ High heat input■ Wide range of material■ Low cutting speed
