Thermite welding
Thermite welding is a technique used to weld rail tracks together at an extremely high temperature (almost 3000°C) using thermite, a mixture of iron oxide and aluminum powder. The residue of the thermite, which mainly consists of liquid iron, is mixed with the iron of the rail tracks at a high temperature through a mold attached to the rail tracks to be welded together.
Processes: SKS, SKV, SOW5
Arc welding
Arc welding is a welding method in which a butt joint is created using special electrodes with increased liquid slag and reduced slag volume.
Build-up welding / repair welding
Repairing rail tracks after wear, breakage, or impact damage has occurred, for example at slip sites.
Adhesive welding
Electrically isolated bonded welding. Two types can be distinguished:
- Prefabricated insulated bonded welding that is assembled and bonded in the factory, also known as prefab.
- The same prefabricated insulated bonded welding, supplied as a package, which can be assembled and bonded in the workshop, on site or on track.
