EXOWELD is the brand name of exothermic materials which are manufactured by Korea EMI Technologies co, Ltd. EXOWELD Exothermic welding is a cost effective method of completing a high quality electrical connection. The process is simple to follow and through the use of a high temperature reaction a long lasting, quality electrical bond is created between conductors. Advantages: 1. Does not deteriorate with age since the connections are permanent. 2. Does not loosen as the ThunderWeld connections create a permanent molecular bond. 3. Excellent corrosion resistance. 4. Electrical characteristics are higher than typical mechanical connections. 5. Does not increase resistance above that of the conductor. 6. No external power or heat is required to make connections. 7. Quality can be assessed visually. 8. Easy and simple to install.
