Huadian exothermic welding materials is to melt the metal conductor through the high temperature produced by the oxidized metals in the reductive flux during the exothermic reducing reaction. This series of products include exothermic welding moulds, mould Handle clamp, exothermic welding flux and supporting operation Tool kit.
1. Good mechanical performance
Solder joint non-surface joint, there is no residual stress, permanent joints, good tensile strength and other mechanical properties.
2. Strong current load capacity
Solder joints and metal conductors are molecular binding. The solder joint current carrying capacity equal to conductor and it have good conductive properties. DC resistivity change close to zero after the welding point.
3. Resistant to large repeated current
Solder joints ’melting point is equivalent to the conductor, can withstand repetitive high current (fault) the impact, the joint no fuse phenomenon.
4. Strong anti-corrosion capacity
The copper bind and cover with the conductor closely, isolation protection from the joint, and thus greatly enhance the corrosion resistance of the conductor.
5. Convenient and safe construction
Without outside energy, professional equipment and professional welding operator, it can be operated safely indoors and outside, short welding time saves construction time.
6. Controllable welding temperature
According to the performance characteristics of metallic conductors, the product can achieve different reaction temperatures (up to 3400 ℃) by adjusting the ratio of the flux, solder joints to ensure a solid and reliable.
PRODUCT OPERATION PROCESS
1. Exothermic Welding Cartridge
Exothermic Welding Cartridge using reducible metal compounds and reducing substances in certain proportion and made through a special process. The flux is non-dangerous goods, physical properties, can be used in any mode of transport.
2. Thermal welding mold
Thermal welding mold is made of high temperature, semi-permanent high-purity graphite produced. It have: mold cavity, mold holes, injection holes and other components. Mold making process should be based on a different shape conductor joint mode (-, T, +, etc.), the shape of the mold cavity, size and flow of the molten metal and rigorous design made of. According to required specifications welding flux, mold divided into four categories mold. For special requirements, Mold can be customized according to the joint mode and the required welding flux model.
3. Welding Mold Holder
During welding process, the adjustable self-locking mold folder can ensure the welding mold clamp tightness, maintaining the mold’s cavity relatively sealed. According to the design requirements, the weld point rapid prototyping.Mold folder according to design requirements can be common. The special mold folder needs to be customized according to the special requirements of the mold.
HD-RM05 Special Mold
4. Welding Toolbox
In the welding construction process, we need use special tools to adjust the mold and folder, insulated protective by work gloves, vegetable brush to clean the mold cavity and the joint surface. All welding tool be in the toolbox.
The product can be widely used in the communications industry, power systems, building systems, military installations, railway systems, broadcasting systems and other equipment industries, the AC and DC work, safely protected, especially suitable for harsh surface environment, corrosion resistance requirements to ground engineering, its market prospect is very broad.
