Manufactured for dependable connections
Aura Weld® exothermic welding powder
A precisely measured weld material for forming permanent, low-resistance connections in grounding, earthing, bonding and lightning-protection systems.

Direct answer
What does exothermic weld material do?
When used in the specified graphite mould, the weld material produces the heat needed to create a molecular bond between conductors. The completed connection is designed to provide lasting electrical continuity without relying on bolts or an external power supply.
Available sizes
Measured cartridges for specified moulds
Select the cartridge shown for your connection and mould. Do not estimate the charge by visual size.
System components
Three essentials inside the mould
Weld material
The specified charge creates the molten metal that forms the connection.
Starting material
Used to initiate the reaction according to the supplied instructions.
Steel disc
Retains the weld material in the crucible before ignition.
Selection checklist

Frequently asked questions
Exothermic welding powder FAQs
What is exothermic welding powder?
Exothermic welding powder is the measured weld material used inside a compatible graphite mould to form a permanent molecular connection between specified conductors.
Which exothermic welding powder size do I need?
The required cartridge size depends on the connection type, conductor material and size, and the graphite mould specification. Use only the size specified for the selected mould.
What affects exothermic welding powder price?
Price is influenced by cartridge size, order quantity, packaging, destination and the complete system requirement. Request a quotation with conductor and connection details for accurate pricing.
Does exothermic welding require an external power source?
The exothermic reaction does not require an external electrical power source. The work must still be carried out by trained personnel using the specified equipment and safety procedures.
How should weld material be stored?
Keep cartridges sealed, dry and protected from moisture, heat and physical damage. Follow the storage and handling instructions supplied with the product.
Can weld powder be used with any graphite mould?
No. Weld material and cartridge size must match the graphite mould and connection specification. Contact Amiable Impex when selecting a system for a new conductor configuration.
