Oxygen is used as the cutting gas for laser burn cutting. During the separation process, the oxygen introduces additional heat into the workpiece due to the localized oxidation of the basic material in the cutting joint, thereby accelerating the cutting process.
Laser burn cutting is ideally suited for manufacturing parts quickly and efficiently, whose visual appearance will continue to change due to subsequent surface finishing processes.
Laser fusion cutting has the advantage of producing a virtually oxide-free cutting edge. The cutting gas is an inert gas. Inert gas blows the molten material out of the separating joint and cools the cutting edge.
Laser fusion cutting is used if workpieces must fulfill high visual requirements without further processing. If subsequent alterations of the material are unwanted, then hygiene and laboratory engineering aspects must also be taken into consideration.
Laser remote cutting (sublimation cutting) is the laser cutting of very thin and sensitive materials, which are cut without the use of cutting gases.
This means that the laser alone evaporates the material, thereby removing the material layer by layer and creating a very thin cutting gap. This process offers unique solutions for processing a wide range of very different composite materials.
