Flame cutting

Flame cutting is one of the hottest metal cutting techniques. Process uses a combination of pure oxygen sources to cut metal

First, the metal is preheated to a very high temperature, and the cutting machine discharges oxygen onto the heated surface. This oxidation process burns the metal into the desired shape and size

Oxygen cutting

Gas cutting is a technique with a long tradition that is constantly being improved and developed. Oxygen cutting is one of the most popular methods for machining steel, most commonly low alloy and mild steel. It is also used to cut metal sheets that are corroded or in packaging. The gas cutting process is used where it is necessary to cut steel of considerable thickness, maintaining accurate results and high efficiency

Oxygen cutting - technical features

This type of cutting process involves heating the surface of the machined material to ignition temperature. The next step is to supply oxygen under high pressure. For correct cutting results, the cleanliness of the cut should be at least 99.5%

Due to these two actions, the treated material is oxidized and blown out of the crack. Generates heat of combustion and heats deep layers to ignition temperature. Therefore, the rest of the process takes place in-house to cut the workpiece. To perform the gas cutting process properly, a specially designed torch that mixes gas with oxygen should be used

Oxygen cutting is not suitable for machining certain materials. This is caused by flash point. In the case of pure iron, 1050°C. When we try to treat the steel with a 1.5% carbon mixture, the temperature rises to 1380°C. Therefore, gas cutting is suitable for cutting low carbon and low alloy structural steel

Oxygen cutting. What kind of gas is used?

The fuel gas used to create the flame is also important to the cutting process. The most commonly used gases are acetylene, propane and natural gas. Oxyacetylene cleavage can reach very high temperatures in a short period of time. Economy customers choose the oxypropane cutting method because it saves some money when fast heating is not required
