Exothermic Welding

Exothermic welding, as a safe, efficient, and excellent metal connection process, is the standard way to connect the ground grid in the grounding system. The metal is melted by the high temperature generated by the aluminothermic reaction, so as to obtain a higher quality welding effect.
