Referring to the permanent jointing technique known so far!

The advanced earthing system employs exothermic welding connections to make joints. This technique leads to the formation permanent molecular link for conductors. This simple and efficient methodology is compatible with copper, steel, brass, gunmetal, cast iron, etc. Earlier, we used bolting, brazing, crimping -  which were some of the jointing techniques known to the people. These traditional methods make highly porous bonds which leads to faster corrosion. Hence there came the need for technological advancement.

What is exothermic welding process?
This is an important stage in earthing installation which is used to join two conductors and to make electrical connections. It is a crucial process which determines the continues flow of current which does not require any external heating provision. This is done to link bar to bar, bar to cable, cable to cable, surface connections, bar to vertical ground rod, and many more. Resulting homogeneous bond guarantees longer life. They do not deteriorate or damages with time. An all-purpose graphite mold is designed according to the type of joint to be made and also considering the material of the conductor.
Joints formed:

•    Tee joint
•    Full Cross joint
•    Half Cross joint
•    Parallel connection
•    Straight joint
•    L joint, etc.




Procedure
Before beginning the process – you must be well aware about all the safety measures. You would require an exothermic welding jointing kits which involves – Graphite mould, welding power, handle clamp, flint gun, mould brush, clamp brush, mould scraper and file card brush. Firstly, clean the surface of mould and the conductors. Then position the conductors inside the mould. Before closing the mould - pour weld powder which consist of welding powder and starting powder. Close the lid. Then using a handle clamp hold the conductors locked inside mould. Ignite the powder using flint gun. Heating of the powder creates a chemical reaction. Finally, after this chemical reaction a mechanically strong link is formed.

Features
•    Advanced method ensuring high electrical conductivity.
•    Non-porous bond formation.
•    Non-corrosive and also withstand extreme temperature.
•    Does not get impaired with time.
•    Enhances the earthing installation.
•    Compliance - IEEE 837, UL 467, National Building Code 2016.

Your choice of an appropriate conductor and enhancement compound will be ineffective until and unless you connect and secure them well with a suitable welding system.

The guaranteed results when it comes to jointing is always labeled as the exothermic weld joints. Jointing is required in various shapes as per the concern. To build such strong connection joints, JAMWELD toolkit creates a vital role. The incorporation of the desire joints is accessible with the help of exothermic welding kit. The kit contains the abundant components that provide stable solution for endless jointing. 1.        Exothermic Welding powder   In the welding powder, the mixture of the metal oxide and copper compound both builds a sturdy joint that create an abiding connection. 2.        Exothermic Welding Mould The mould is constructed with a graphite mould that oversee the molten weld flow and form an exothermic weld joint. 3.        Exothermic Welding Handle Clamps In the exothermic welding, the handle clamp is a safe initiate that should be used properly during the formation of the joint. It helps to carry the mould tightly. 4.        Exothermic

The main purpose of the earthing system is to provide a path for fault currents to flow and dissipate into the ground which work as safety measure to protect human life as well as equipment. The joint and connection plays an important role in an effective earthing system. The JAM WELD Exothermic welding kit provides a definite molecular bonding among two or more metallic conductors to join them permanently having same or different cross-sectional area. This can be held by the process of exothermic reaction. The difficulties that have been encountered in conventional method of welding and jointing are: - jointing failure due to less contact surface area and aging due to atmospheric corrosion. These problems are removed when exothermic solution comes in practice. It requires no external heat or force in its procedure. Unlike mechanical joints, the connection provides 100% contact surface area. This jointing can be made in between copper to copper, copper to steel etc. The exothermic

Exothermic welding to enhance the integrity and longevity of the weld

Every one now is familiar with the earthing techniques and the components used in the technique. Earthing technique and electrical safety provisions is around us since thousands of years. Conductor dug deep inside an earth pit surrounded by soil enhancing compound can deliver earth connection. This connection to the conduction part of the ground to achieve electrical contact is referred to as earthing.It is a necessity in almost every industry for every electrical/electronic component. Electrical faults are unpredictable issue which can be disastrous if there is no appropriate protection system installed.Connection of the equipments to the ground is a tedious process and need to given proper care as once the connections are established, they are expected to stay so for a really longer service life. Exothermic welding system is the only permanent way to joint two or more dissimilar conductors. Conventionally, we made use of techniques such as crimping, brazing, bolting, and va
