Special materials

Grey cast iron, (GG/EN-GJL)/(GGG/EN-GJS), Aluminium, Bronze, Austenite, etc


With these steels, the welding repair requires special craftsmanship, since the usual welding parameters cannot be applied. In addition, special welding accessories are optimally adapted to the material or the alloy.


Grey cast iron

  • Spec. Requirement of the welding technique by joining the welding filler and the basematerial
  • Beachtung von Homogeneanbindung da Gefahr von Anbindungsrissen an den Korngrenzen entsteht.


Austenitic steel / high temperature steel

  • Precision at welding high temperatures
  • Risk of hot cracking
