Exothermic weld is a very efficient and cost efficient method of making large or small numbers of high quality electrical connections. Exothermic weld is a simple self-contained system that uses the high temperature reaction of powdered copper oxide and aluminium, within a mould, to form permanent electrical connections.
The exothermic weld system requires no external power or heat source, creates high quality electrical connections, is completely portable, can be used safely with minimum training, is cost-effective and can be used for over 45 standard connection configurations. exothermic weld connections have several advantages in that they are tolerant to repeated faults, are highly conductive, do not loosen and have excellent corrosion resistance because of the very high copper content (>90%) of the alloy.
Amiable Impex was the first Company in Mumbai to introduce and supply Exothermic Weld Powder and Accessories. Exothermic Welded electrical connections supply from us will never loosen, corrode or increase in resistance. We are one of the largest importer of Exothermic Weld Powder in India. Due to our Superior and Best Quality we are able to sell our product to Railways Contractors, Rail Metro, Telecommunications, Earthing and Lightning Installers Industries, as well as to Electrical Suppliers etc.
Exothermic weld is a simple, efficient, high quality metal connection method , Exothermic welding by aluminothermic reaction generated by high temperature to make completely molten metal, in order to achieve high quality welding effect. This reaction is conducted in the graphite mould of high temperature resistance, exothermic reaction process takes only a few seconds.
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.
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.

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.
The process of igniting the particles creates extremely high heat i.e upto 2000 degree Celcius and produces Exothermic Reaction which also melts the Steel Disc and then the Exothermic Weld Powder flows into the Weld cavity thus filling any available space and completes the Weld. In Weld cavity the molten copper alloy partially melts the conductors. The molten copper alloy gets cooled and forms a fusion Weld which solidify before it is removed from the mould.
This entire process takes only upto 10 to 15 seconds to complete. Then the mould is ready for the next Weld after a brief cleaning with a brush. Exothermic Welded connections produce a permanent connection, superior in performance to any known mechanical or pressure type surface-to-surface contact connector. Due to the fact that the connection produced is a molecular bond so an exothermic Welded connection will not loosen and there will be increase in resistance over the lifetime of the installation.
The Process is very Simple and hence a Laymen can do the Job Work by just seeing the process once. Hence one need to ensure that the process should be undertaken carefully and proper instruction should be maintained by the Laymen. For more details please visit our page of Exothermic Weld Process
Exothermic weld is a process that achieves the molecular binding among two or more metallic conductors by a chemical reaction. This molecular binding improves mechanical, electrical and anti-corrosion properties compared with any mechanical connection. exothermic weld is the best way to make permanent, reliable and high conductivity connections for any installation requiring an earthing system.
It is ideal for the following application:
Hence this Exothermic Weld Powder is used in Grounding & bonding and lightning protection in Power plants , Substations , Transmission line , Refinery , Industrial plant , Commercial plants , Telecommunication tower , Building , Housing etc.
According to the customers specification and requirement any shape Joints is Possible through our innovative design of Graphite Moulds.
Amiable Impex was founded with the goal of being at the forefront in the Electrical Metal Industry in both India and overseas. Since our foundation, the company has grown through continuous development.
