What is Exothermic Weld?

“Exothermic weld” is a simple, cost-effective and permanent welded connection that uses a high-temperature exothermic reaction to create a molecular bond. It does not require an external heat or power source. Exothermic weld is the universally preferred method for making permanent copper-to-copper and copper-to-steel electrical connections. Its performance is superior to all existing surface-to-surface mechanical connectors. “Exothermic weld works when others won’t!”

In every business, in every industry, management does matter.

What is Exothermic Welding ?

Exothermic Weld System is a very effective and cost efficient method of making electrical connections in high quality which includes Large Connection or Small Connection. It is a simple self-contained system that uses the high temperature reaction of powdered copper oxide, aluminium and other required chemical and materials, within a mould to form permanent electrical connections.


What and Which Metal can be Weld through Exothermic Weld Powder ? The process of exothermic Weld is a method of making electrical connections from Copper to Copper or Copper to Steel and it can join any Metals to Metals like Bronze, Galvanized metals and Stainless steel etc , in which no outside source of heat or power is required.

What is the Process for Exothermic Weld ?

In Exothermic Weld Process, the following are the steps :

  • Step 1 – The two conductors that is to be joined are placed in the Weld cavity and than the steel disc is located in the base of the crucible in the Graphite Mould.
  • Step 2 – After the disc is placed in the Mould, Exothermic Weld Powder Material is poured down into Graphite Mould followed by Starting Powder
  • Step 3 – Some Ignite Powder should also be sparkled on the Mouth of Mould and than ignited by Flint Gun.

    Why Use Exothermic Weld ?

    The Exothermic weld Connecting created a permanent, homogeneous, and molecular bond that cannot loosen or corrode over the lifetime of connection. The same cannot be said about other methods - such as brazing, crimping, split bolt, or compression type connections.

    Advantages and Disadvantages of Exothermic Weld:

    Compared for some other forms of welding, exothermic bonds employ a greater mechanical toughness. The weld can be proof against corrosion. You simply won’t notice an increase in electrical excess weight despite repeated small signal pulses; your weld is highly firm. The procedure is more costly, however. The task requires replaceable moulds, is not easily repeatable.

    Exothermic weld may also be done far from others. That reduces dangers to employees. A igniter is used with widespread graphite molds or a palatable made drop within weld metal ink cartridge, semi-permanent graphite crucible pattern, and an ignition company that connects your container with a cord.

    Exothermic weld is usually used for welding copper conductors but is suitable for welding a wide range of metals, including stainless steel, cast iron, common steel, brass, bronze, and Monel. It is especially useful for joining dissimilar metals.

    Exothermic welding Method

    Exothermic Welding is a simple self contained method of making high quality electrical connections for welding copper to copper, copper alloy such as brass, bronze or copper to steel.

  • The Exothermic Welding system uses the high temperature of reaction of powdered copper oxide and aluminium.
  • The reaction takes place in a graphite mould, which is machined according to the conductor sizes to be welded and which can be used for approx.
  • 60 welds or more welds if properly cared for.
  • The reaction last a few seconds only and the process requires no external power or heat source, making it completely portable and ideal for field use.
  • Typical applications include earthing of sub-stations and power plant, cathodic protection, rail connections, lightning protection, telecommunications, etc…
  • An Exothermic Welding shows a lot of advantages in comparison to mechanical or crimping systems.
  • As it is a molecular weld it will not be affected by high current surge. It can be shown by tests that the electrical conductor will melt before the Exothermic weld when subject to high short circuit current.
  • The weld metal has the same melting point as copper and the cross section of the weld is higher than the cross section of the conductors to be welded so that the current carrying capacity is greater than that of the conductors. In addition to copper material such as brass, bronze, stainless steel, steel rail, etc… may also be welded.
    The result will be a connection composed of an alloy without dielectric influence at the exothermic weld point and totally unaffected by corrosion.
