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 various other compression methods – all these methods were later proved to be create low quality welds. These methods can hamper the functioning of the installation as they get loose and damaged over time. The rate of corrosion is also high for these methods as they make highly porous joints.
For better conductivity, longevity and electrical conductivity parameters the conventional methods were gradually made obsolete and that gave way for exothermically welded joint.They make a low resistant joint with 100% contact surface enabling continuity in the electrical network. All the small and heavy connections in the earthing installation need to be proper, effective and long lasting.Maintenance free earthing system utilize this connecting scheme as they enhance the weld resilience and forms a perfectly finished joint with zero defect.This technique is applied universally owing to other parameters such as – ability to withstand repeated voltage spikes without any failure.
