Oxidizing cutting

Oxidation cutting is a thermal cutting method used to cut metal, mainly non-alloy and low-alloy steel. The method is based on a chemical reaction where the material is heated to ignition temperature and then reacts with a pure oxygen jet. The result is an efficient cutting process that is particularly suitable for coarser materials and larger steel structures.

Despite its long history, oxidation cutting remains an important method in engineering, steel construction, repair, dismantling and heavy manufacturing. It is appreciated for its simplicity, its capacity to handle thick materials and its relatively low equipment cost.

Laser cutting with assist gas, what does it mean?

Laser cutting with assist gas is a common concept in modern sheet metal processing. It involves using a gas in conjunction with the laser beam to enhance the cutting process, influence the cut quality and control the outcome depending on the material, thickness and subsequent processing requirements. Common options are oxygen, nitrogen and compressed air, with each gas having its strengths depending on the application and desired end result. According to laser system manufacturers, assist gases are used to blow molten material out of the cut, influence the reaction process in the cutting zone and optimize quality or speed.

At the same time, it is important to be clear about how this relates to Thor Ahlgren's offering. Thor Ahlgren does not market laser cutting with assist gas as a separate service in the way that some more process-niche players do. Instead, the company offers sheet metal laser cutting, 2D laser cutting, tube laser cutting and complementary post-processing, with a focus on high repeatability, tight tolerances and a stable production flow from prototype to series.

Fusion cutting, melt cutting 

Fusion cutting is an effective laser cutting method when you want high cutting speed, good edge quality and a process that is well suited for both prototypes and series production. At Thor Ahlgren AB, we use fusion cutting to produce parts with stable quality and repeatability, where the cutting result works directly in the next step, such as bending, welding or assembly. 

The method is particularly relevant when you want to avoid oxide in the cut surface and get a clean, smooth edge with minimal rework.

Laser tube cutting 

When you work with tubes, profiles and hole patterns that need to fit precisely, tube laser cutting is an effective way to produce parts with high precision and good repeatability. At Thor Ahlgren AB, we help you produce tube and profile details that are right from the start, whether for prototypes or series production. 

Laser tube cutting makes it possible to integrate several operations into one process. This can reduce the need for drilling, sawing, deburring and fixturing, while creating a better fit and faster assembly in the next step.
