What Is The Difference Between Exothermic Welding Mold And Fire Mud Welding Mold?


Exothermic welding molds are made of high-purity graphite and are used to form the welding head for grounded exothermic welding. A complete mold consists of a mold body, a top cover, and a hinge. It is very suitable for the welding of cables and other metal components in the field, and is suitable for the connection between copper core cables and steel structure welding or copper core cables during the installation of cathodic protection systems.


Exothermic welding is a simple, high-efficiency, and high-quality metal continuous welding process. It uses the chemical reaction heat of metal compounds as a heat source, and works through superheated (reduced) molten metal, direct welding or indirect welding. The cavity of the graphite mold forms a welding head with a certain shape and size that meets the engineering requirements. At present, exothermic welding has generally replaced the mechanical continuous welding method between metals in the past.
