Crucible systems

Suitable for all Original Thermit® welding processes

As an end-to-end supplier for the aluminothermic welding we develop, produce and supply crucible systems that are needed for the Original Thermit® welding processes.

Single Use Crucible I for Original Thermit® welds

The complete single use crucible I is ready to use and enables fast, flexible work. It ensures a high degree of process reliability, and therefore ensures the quality of the rail. The single use crucible I consists of a tin bucket with a fireproof crucible lining and an automatic tapping closure – other packaging is not required. The single use crucible, charged ex-factory with a Original Thermit® portion, is the safest version and is therefore the most frequently used version worldwide. A tightly closing cover prevents moisture from getting in.


  • Crucible lining and Thermit® portion are reliably protected against moisture
  • Low weight and ease of use, resulting in optimised work processes
  • No further preparation required unlike other crucible systems, reducing sources of potential errors
  • After welding has taken place, the crucible can be used for disposing of welding residues

Long-life crucible for Original Thermit® welds

The long-life crucible is designed to be used several times. It ensures safe execution of the Original Thermit® weld, is cost-effective and also environmentally friendly. A tapping thimble, which opens for every Original Thermit® weld to be used, ensures a safe welding process. To increase the crucible volume for wide gap welds, a larger crucible extension ring is available.


  • Cleaning the crucible lining after 15 castings on average
  • All components of the long-life crucible system are available separately
  • Low quantities of waste and therefore low disposal costs
  • Used for all common rail profiles
  • Standard and wide gaps (L50, L75) can be welded
