The hot melt soldering method is a permanent joint that utilizes a reaction between the compounds to generate a high temperature, and the molten metal passes through the investment mold to reach a welded portion and forms a shape that conforms to the process requirements. This method allows welding between copper and copper, copper and steel, copper and galvanized steel, the same metal or different metals.

In order to weld between different types of conductors and different types of conductors, it is necessary to make a special mold for welding. Fix the two ends of the welding conductor in a mold, put in the hot melt flux, ignite the ignition powder, react to produce high temperature to melt the powder into liquid, and after cooling, open the mold, and the welded conductor becomes a permanent connection. Our company has matching molds for different hot melt flux specifications.

Fire mud welding, exothermic welding products performance characteristics:

1. Large current load capacity

The current-carrying capacity of the fusion splice is the same as that of the conductor, and it has good electrical conductivity. After testing, the DC resistance ratio changes before and after welding are close to zero. This is unmatched by any traditional connection method.

2. Good mechanical properties

Because it is a fusion joint, the joint is a molecular bond with the conductor and is a permanent joint.

3. Impact resistance is stable

Experiments have shown that under short-term high current impact, the conductor melts before the joint and thus does not receive damage from the inrush current.

4. Strong corrosion resistance

Since it is a fusion joint, no contact indicates that there is no residual stress, and the joint is covered with pure copper, thereby greatly enhancing the corrosion resistance of the conductor.

5. Freely regulate the reaction temperature

No external energy, no special equipment, no professional operators, indoor and outdoor operation, and short time to complete the connection process.
