AxiWeld Exothermic Welding is a simple, cost effective, self contained and portable process of forming high quality and permanent metal-to-metal connections.The AxiWeld line of Exothermic Welding products are manufactured and tested in accordance to IEEE 837.

AxiWeld offers moulds which can make the following connections:
- Cable to Cable
- Cable to Ground Rod
- Cable to Steel Surface
- Busbar to Tape
- Tape to Cable

Through the Exothermic Welding process, connections are made by a reaction of a powdered copper compound and aluminium which allows superheated molten copper alloy to form on and around the conductors to be joined. The final connections are electrically conductive due to their high copper content and have strong corrosion resistant properties. The exothermic welding process can be used to weld materials for electrical purposes including but not limited to: Stainless Steel, Brass, Copper, Bronze, Galvanized Steel, Steel Rail, Cast Iron and Copper Clad Steel.

Procedure for Exothermic Welding

You can watch the following video to learn how to make quick long lasting connections using the AxiWeld system!

In case you can't watch the video above, you can use the following procedure to make sure you correctly use the AxiWeld Exothermic Welding System.

1. Identify the correct mould for which the joint has to be made.
2. Identify the correct weight of welding powder from the datasheet of the mould.
3. Identify the correct brush to clean the conductors or strips.
4. Clean the mould using brush and scrapper if required.
5. Preheat the mould.
6. Fix the mould onto the Handle clamp.
7. Clean and prepare the site for excess dirt, sand etc.
8. Ensure that there is sufficient clearance between ground and Clamp / mould at site for easy opening after joint formation.
9. Avoid loading effect of continuous running cables on mould. Uneven cable weight will create gap inmould and allow molten metal to leak, resulting into improper joint. (Create support wherever required to keep conductors aligned.
10. Locate the conductors within the mould.
11. Close and lock the mould using the handle clamp.
12. Seal the conductor openings on the mould using the mould sealing compound. This restricts the outflow of molten metal during the welding process.
13. Place the steel retaining disc in the mould cup above the top hole.
14. Pour the required amount of weld powder into the mould cup.
15. Pour the starting powder such that it makes a path till the lip of the mould.
16. Close the mould.

17. Make sure the technician has worn gloves and safety glasses before igniting the powder.
18. Ignite the starting powder from the side using the flint gun
19. Allow the mould and joint to cool down.
20. Open the mould.
21. Use appropriate tools to carefully remove the welded joint from the mould.
22. Clean the joint and remove any excess slag.Congratulations!

Congratulations! You have now successfully joined the two conductors!
