Earthing & Grounding
Cable-to-rod and bar-to-rod joints create permanent paths to grounding electrodes.
Engineered connection geometries
Graphite Mould Joints for Permanent Electrical Connections.
Amiable Impex manufactures AURAWELD® exothermic welding powder, precision graphite moulds and field accessories for reliable grounding and bonding connections.
Common exothermic weld joints are organised by the conductors being connected. Cable-to-cable, cable-to-ground-rod, cable-to-bar, cable-to-surface, bar-to-bar and bar-to-ground-rod moulds support straight, tee and cross geometries across electrical, structural and infrastructure projects.

Where common joints are used
Connection Families for Critical Infrastructure.
The correct joint geometry helps maintain dependable electrical continuity across grounding, power, rail, telecommunications and structural-bonding systems.
Power Distribution
Cable-to-bar and bar-to-bar joints support reliable current transfer in electrical assemblies.
Structural Bonding
Cable-to-surface joints bond grounding conductors to steel or copper structures.
Rail & Signalling
Specified cable connections support electrical continuity in railway infrastructure.
Telecommunications
Grounding and bonding joints protect towers and communication equipment.
Corrosion Protection
Permanent welded connections support selected pipeline and cathodic-protection systems.

Common joint selection answers
Quick Technical Guidance.
01What are exothermic weld common joints?
Exothermic weld common joints are standard conductor configurations formed inside a purpose-designed graphite mould. They include cable-to-cable, cable-to-ground-rod, cable-to-bar, cable-to-surface, bar-to-bar and bar-to-ground-rod connections.
02How is the correct graphite mould selected?
Selection begins with the conductor materials, conductor dimensions, required joint geometry and installation orientation. These details determine the mould family, mould code and matching weld-metal charge.
03Can one graphite mould be used for every joint type?
No. The mould cavity is engineered for a defined conductor combination and joint geometry. The specified mould and weld charge should be used for each connection.
04Which details should be shared for a joint recommendation?
Share both conductor materials, their sizes, the required straight, tee or cross arrangement, project quantity and installation conditions. This allows the mould and weld-metal system to be matched correctly.
Need a non-standard connection?
Share the Conductors. We’ll Help Match the Mould.
