All You Need to Know About Exothermic Welding System

Before introducing Exothermic Welding System, firstly you have to be aware about Exothermic welding process. This process is basically a welding process of joining materials that employs molten metal to permanently join the conductors. The process use an exothermic reaction of a thermite composition to heat the metal, and requires no external source of heat or current. It is very efficient method of making high quality electrical connections. Moreover, it is used to create electrical molecular bond between different metals such as cooper to cooper, aluminum to copper etc.

This Exothermic Welding System is very cost effective and efficient method of making large number of high quality electrical connections. Moreover, it is a self contained system that utilizes high temperature reaction of aluminum, copper oxide within a mould form. This system contains Graphite mold, Metal disc, Fastening clamp, powder, Steel brush, Banister brush, etc. Exothermic Welding Powder is included in the Exothermic Welding Kit.

When it is used:

Exothermic Welding Equipment is most commonly used for permanently joining copper conductors. It is the only acceptable means of bonding copper to:

• Stainless Steel
• Copperweld
• Nichrome V
• Galvanized Steel
• Silicon Bronze
• Copper Clad Steel
• Columbium
• Plain Steel
• Everdur
• Kama
• Steel Rail
• Cor-Ten

Exothermic Welding Graphite Moulds or simply Exothermic Welding Moulds are available to suit your application. Its particular application includes:

• Cathodic protection
• Earthing for power plants & substations
• Rail connections
• Telecommunications
• Transmission & power distribution lines
• Residential Power Systems Grounding

Its good electrical conductivity and high constancy in the face of short-circuit pulses is commendable, therefore its one of the option mentioned by United States National Electrical Code for grounding conductors and bonding jumpers. Furthermore, this system has been shown to be the ideal choice where safety, dependability, longevity and current carrying capacity are critical.

The first thing I want to say about this system is its higher mechanical strength and its stability when subject to repeated short-circuit pulses. It’ s also not suffer from increased electrical resistance over the lifetime of the installation. This system produce a permanent connection, excellent in performance to any known mechanical or pressure type surface-to-surface contact connector.

Features:

• Excellent electrical conductivity to the conductors themselves.
• Does not oxidize, corrode or degrade with time and is resistant to galvanic coupling.
• Able to withstand repeated electrical discharges.
• Never increases its resistance.
• It assure the most common connections not only between copper cables but also for metallic pieces and welding tapes made of stainless steel, brass, and copper coated steel earth rods.
• Has greater mechanical and squeezing resistance than the conductors themselves.
