Hot-melt flux is a new type of welding technology used as the main grounding material for the grounding network. The main characteristics of high-quality hot-melt flux are strong, full, non-bubble, strong conductivity, and not easy to corrode. The specific performance is as follows: 1. Welding The appearance of the joint shall be free from defects such as sharp corners, nicks, curling. 2. There is no honeycomb pore in the fusion interface. 3. No cracks on the joint. 4. Welded joints should be firm, free from looseness and voids. 5. No exposed welding parts. 6. The welded joint is cut open, and fusion bonding (molecular bonding) is required between the welded part and the welded part. 7. No honeycomb pores.

Introduction to hot melt flux (mold) welding method:
The hot-melt flux welding method uses the reaction between the compounds to generate high temperature, and the molten metal reaches the welding position through the investment mold and forms a certain shape, and the size of the joint meets the requirements of the process.This method can weld copper and copper, copper and steel, copper and galvanized steel, the same metal or different metals.
In order to weld between different specifications and different types of conductors, a special mold needs to be made for welding.The two ends of the conductor to be welded are fixed in a mold, hot melt flux is placed, the ignition powder is ignited, and the reaction generates high temperature to melt the powder into a liquid. After cooling, the mold is opened, and the conductor to be welded becomes a strong connection.Our company has corresponding molds for different hot melt flux specifications.
Performance characteristics of exothermic fusion welding products:
电流负载能力大1.Large current load capacity
The welding point has the same current carrying capacity as the conductor, and has good electrical conductivity. After testing, the change in the DC resistance ratio before and after welding is close to zero.This is unmatched by any traditional connection method.
机械性能良好2.Good mechanical properties
Because it is a fusion joint, the joint and the conductor are molecularly bonded, and it is a kind of strong joint.
Experiments show that under the impact of large current for a short time, the conductor melts before the joint, so it will not be damaged by the surge current.
Because it is a fused joint, no contact indicates that there is no residual stress, and the joint is covered by pure copper, which greatly enhances the corrosion resistance of the conductor.
自由调控反应温度5.Freely control the reaction temperature
No external energy, no special equipment, no need for professional operators, indoor and outdoor can be operated, and the time to complete the entire connection process is short.
连接简单、安全6.Simple and secure connection
According to the metal characteristics of the conductor to be welded, different reaction temperatures can be configured to make the welded joint stronger and more complete.
