There are various methods available to establish connections including – crimping, brazing, bolting, and compression techniques, etc. which does not ensure a long term fix as it may break or get loose with short span of time. When in case of reliability and longevity, Exothermic welding is the right pick that leads to creation of a joint with 100% contact surface. You can create any form of joint namely- Straight joint, Tee joint, parallel joint, cross joint, etc. utilizing exothermic welding kit. Connection being proper is a mandate to every protective circuit as the connection failure or accidental disconnection can lead to catastrophes.
For the rail welding in the railroad constructions, exothermic welding system is the only method that can assure rail safety. The casting is done in a purpose made graphite mould. The mould is prepared as per the dimension and the type of joint that is to be made. The conductors are cleaned using the brush to remove the moisture and then they are well aligned inside the mould to enhance the quality of the joint. Further, the mould is filled with welding powder that melts and forms a stronger and long lasting connection offering high current carrying capacity. Being a permanent solution, they do not corrode or get loosen. The method is highly recommended as connection making and the inspection process is quite simple and quick.
