Exothermic weld
is also known as exothermic bonding, thermite welding (TW), and Thermit welding. There are many advantages of using exothermic weld. 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.

Features of Exothermic Weld:

  • It has Superior electrical conductivity to the conductors themselves.
  • It does not corrode, oxidize or degrade with time and is resistant to galvanic coupling.
  • It is able to withstand repeated electrical discharges.
  • It never increases its resistance.
  • It has greater mechanical and squeezing resistance than the conductors themselves.
  • It Offers  a  permanent  welding  and  a  low  resistance   connection,   essential  for  achieving longwearing and trustworthy  results in earthings.
  • 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.




 

Process of Exothermic Welding

The Exothermic Welding Process is a simple, self- contained method of forming high quality electrical connections. The compact process requires no external power or heat source, making it completely portable. Connections are made inside a semi-permanent graphite mould using the high temperature reaction of powdered copper oxide and aluminium.  An Exothermic Welds connections is actually a molecular bond formed between two metals such as copper/copper, copper/steel and steel/steel.

Exothermic welding, also known as exothermic bonding and thermite welding is a welding process for joining two electrical conductors, that employs superheated copper alloy to permanently join the conductors. The process employs an exothermic reaction of a copper thermite composition to heat the copper, and requires no external source of heat or current. The chemical reaction that produces the heat is an aluminothermic reaction between aluminum powder and a metal oxide.

The reaction reaches very high temperatures, depending on the metal oxide used. The reactants are usually supplied in the form of powders, with the reaction triggered using a spark from a flint lighter. The activation energy for this reaction is very high however, and initiation requires either the use of a “booster” material such as powdered magnesium metal or a very hot flame source. The aluminum oxide slag that it produces is discarded.

When welding copper conductors, the process  employs  a semi-permanent graphite crucible mould, in which the molten  copper, produced by the reaction, flows through the mould and over and around the conductors to be welded, forming anelectrically conductive weld between them.  When the copper cools, the mould is either broken off or left in place. Alternatively, hand-held graphite crucibles can be used. The advantages of these crucibles include portability, lower cost (because they can be reused), and flexibility, especially in field applications.

The weld formed has higher mechanical strength than other forms of weld, and excellent corrosion resistance. It is also highly stable when subject to repeated short-circuit pulses, and does not suffer from increased electrical resistance over the lifetime of the installation. However, the process is costly relative to other welding processes, requires a supply of replaceable  moulds, suffers from a lack of repeatability, and can be impeded by wet conditions or bad weather (when performed outdoors).

Advantages and Disadvantages of Exothermic Welding :

Compared for some other forms of weldingexothermic 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, which enable it to be impeded by means of poor weather conditions if the work is done out of doors. 

Exothermic welding 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.
