Exothermic Welding is the permanent welding solution that provides the strongest underground joints with the 100% contact surface area. Due to the 100% surface area, the probability of corrosion eliminates from the connection and it serves the best life to the joint.
Exothermic welding is the best replacement to the conventional jointing practices like nut and bolting, brazing, arc welding etc. Highly recommended by IEEE 80, NBC 2016, IEEE 837, UL 467.
