What is the most commonly used method for connecting the grounding network now? Of course it's exothermic welding, why use exothermic welding? What are its advantages? What are the special functions of exothermic welding?

1. The current carrying capacity of the solder joint (welding head) is equal to that of the wire;

2. Because solder joints are made by welding, they are permanent and will not age;

3. Solder joints are permanent molecular bonds that will not loosen;

4. Solder joints are not affected by corrosive products like copper;

5. The solder joint can withstand repeated large surge (fault) currents without degradation;

6. The welding method is simple and easy to train;

7. The materials used for welding are very light and easy to carry;

8. When welding, no external welding power or heat source is required;

9. The quality of welding can be checked from the appearance;

10. Can be used for welding copper, copper alloys, copper plated steel, various alloy steels including stainless steel, and high resistance heating source materials.
