What is flame cutting?
Flame cutting (oxycutting) is a steel cutting process that uses pure oxygen to cause oxidation.
It relies on the chemical reaction between a jet of pure oxygen and the metallic material to be cut. This high-temperature combustion process (over 1300°C) causes the metal to melt, while a stream of oxygen blows away the debris, resulting in clean and precise cuts (+/- 1mm).
Benefits of flame cutting
Oxyfuel cutting offers several advantages compared to other conventional cutting methods like laser cutting, water jet cutting, or plasma cutting:
- Its good cutting quality regardless of the base material's thickness
- Its ability to cut large and medium thicknesses, up to several tens of centimetres
- Competitive costs
- High productivity
We perform flame cutting on various types of alloy and low-alloyed steels.
- Steel: flame cutting is highly effective for cutting steel, including mild steel, carbon steel, alloy steel...
- Stainless Steel: Flame cutting can be used for cutting stainless steel, but this process needs good monitoring of the cut's quality because stainless steel is more prone to deformation.
- Steel Alloys: Alloyed steels, such as high-strength steel or tool steel, can also be cut through flame cutting.

The flame cutting process
Flame cutting, a technique perfected over 30 years at AMDL, follows a strict 3 steps process.
Preheating : Before flame cutting begins, we conduct a crucial preheating step. It's a simple principle; we heat the material to its ignition temperature, which is approximately 1300°C. This is achieved using preheating flames generated by an oxyfuel torch. With our experience, we control this heating to focus on a specific area of the material to be cut. This heating causes a combustion, transforming the steel into iron oxide.
Piercing : Once the material is heated, and the ignition temperature is reached, we proceed with piercing. For this, a stream of pure oxygen is directed towards the preheated area, which will pierce the sheet. The stream of pure oxygen, in contact with the heated steel or material, causes a rapid oxidation reaction, forming a kerf in the steel.
Cutting : After the rapid oxidation reaction has occurred, and the oxygen stream has pierced and passed through the sheet, the torch is then moved at a constant speed according to the defined cutting pattern, allowing for an exact and clean cut. The preheating flame remains active throughout the process, keeping the steel hot and ensuring a sharp and precise cut.
