Copper or Steel Stud to Rail

ERICO CADWELD applications for railway properties utilize the ERICO CADWELD PLUS F80 and the ERICO CADWELD F80 welding material alloys. ERICO CADWELD exothermically welded connections are engineered to provide a permanent, molecular bond that will not loosen or corrode, enabling connection of dissimilar materials. The connections are designed to perform for the life of the conductor and/or installation. The ERICO CADWELD connection has a current carrying capacity equal to or greater than that of the conductor and will withstand repeated fault currents without failing during operation. Once completed, installers can clearly ensure quality by visually inspecting the new connection.


  • Forms a permanent, low resistance connection
  • Provides a molecular bond
  • ERICO CADWELD Exothermic Connections are rated with the same current capacity as the conductor
  • Portable installation equipment with no external source of power required
  • Installers can be easily trained to make ERICO CADWELD Exothermic Connections
  • Connections can be visually inspected

For applications such as computer room, tunnel or other low-ventilation areas, specify a smokeless ERICO CADWELD EXOLON mold. Add an XL prefix to the standard mold part number when ordering (for example, a PB10GR162G becomes XLPB10GR162G). Similarly, ERICO CADWELD EXOLON welding material is also designated by the XL prefix (for example, PB90 becomes XLPB90).
A gap between conductors may be required. See mold tag for more information.
