The exothermic welding mold is made of high-purity graphite and is used for welding head molding for grounded exothermic welding. A complete mold consists of a mold body, a top cover, and a hinge. Exothermic welding is a process that uses high heat generated by exothermic chemical reactions to complete welding. Exothermic fusion welding is also called: fire mud welding, fire mud fusion welding, exothermic welding, thermochemical fusion welding, etc. The welding points are molecularly bonded and will not age and are not easily affected by corrosive products. The welding points have strong current-carrying capacity and can withstand repeated large surge currents without degradation. The welding speed is fast, the welding quality is high, and it saves time and effort. These features are superior to ordinary traditional welding methods.
The exothermic welding process is through the chemical reaction of aluminum and copper oxide< (< Exothermic welding< )< to produce liquid high-temperature copper liquid and aluminum oxide residue, and use the high temperature generated by the exothermic reaction to achieve high-performance electrical welding modern welding technology. Exothermic welding is suitable for connecting copper to copper, copper to steel, steel to steel and other metal materials and equipment. The method is simple, suitable for all grounding system connections, and does not require any external heat source or power supply. This kind of heat can melt the surface of the material to be welded, so the quality of the joint is very high and the use time is very long. At the same time, it has cathodic protection function.
