Exothermic Welding Thermoweld Powder for Metal Conection

Exothermic Welding Thermoweld Powder for Metal Conection

Product Description


Exothermic Welding powder is also known as exothermic bonding, thermite welding (TW), and Thermit welding. There are many advantages of using Exothermic Welding powder. The most important one being that the process produces a molecular joint and not just a mechanical one in between the conductors. It is produced through a starting reactant which provides enough energy to activate the welding reaction. This takes place quickly and safely inside a graphite mould. The mould is designed specifically for a certain union depending on the elements to be welded and the joint type required. We guarantees all types of joints, not only copper cable unions but also to weld tapes, brass metallic pieces, stainless steel, steel ground rods covered with copper, etc. It is especially useful for joining dissimilar metals.




1.It has a superior electrical conductivity than the conductors themselves.

2.It does not corrode oxide or degrade with time and is resistant to galvanic coupling.

3.It is able to withstand repeated electrical discharges.

4.It never increases its resistance.

5.It has higher mechanical and squeezing resistance than the conductors themselves.

6.It  offers  a  permanent  welding  and  a  low  resistance   connection,   essential  for  achieving longwearing and trustworthy  results in earthings

7.It guarantees the most common connections not only between copper cables but also for welding tapes and metallic pieces made of brass, stainless steel, and copper coated steel earth rods.

8.portability, lower cost (because they can be reused), and flexibility, especially in field applications,requires no external source of heat or current.

Operation Step:

Making a WELD joint is a simple procedure as illustrated below:
Step 1Locate the conductors (A) to be joined in the weld cavity (B) and close the mould (C).
Step 2Locate the steel retaining disc in the base of the crucible (D). Pour in the weld powder (E) followed by the starting powder (F). Ignite starting powder with a spark gun.
Step 3The resulting exothermic reaction reduces the weld powder to molten copper alloy which melts the retaining disc and flows into the weld cavity where it partially melts the conductors (G).
Step 4The molten copper alloy cools to leave a fusion weld of great mechanical and electrical integrity.
