What is lightning protection grounding exothermic welding
Exothermic welding powder, exothermic welding mold, 15725212491 lightning protection and grounding professional manufacturer. Exothermic welding is a simple, efficient, and high-quality metal connection process that uses the chemical reaction heat of metal compounds as a heat source. It directly or indirectly heats the molten metal through overheating (reduced) to form a fusion welding joint with a certain shape and size that meets engineering requirements in the cavity of a specially designed graphite mold. Currently, exothermic welding has generally replaced the mechanical connection methods between metals in the past. 1. The current carrying capacity (melting point) of the fusion point is the same as that of the conductor, and it has good conductivity. After testing, the rate of change in the DC resistance ratio before and after welding is close to zero. This is incomparable to any traditional connection method. 2. Welding points are molecular bonds, permanent, and do not age. 3. Welding points are not affected by corrosion like copper. 4. Will not be damaged by high surge currents. Experiments have shown that under short-term high current impact, conductors melt before fusion welded joints. 5. Easy to operate and simple. No need for professional personnel. 6. The equipment is simple, lightweight, easy to carry, and easy to operate. 7. The quality of welding can be checked from the appearance. 8. When welding, no external power or heat source is required. Compared with traditional mechanical connection processes, exothermic welding is a true molecular welding, where the conductor is not damaged and there is no contact surface, and the overall effectiveness of the conductor interface remains unchanged.
