Thermal fusion bonding (also known as thermal welding, soldering clay bonding, or aluminum thermite welding)

Produced through a chemical reaction (exothermic reaction) between copper oxide and aluminum, resulting in liquid at high temperatures.Slag from copper melt and alumina, utilizing the high temperature generated by exothermic reactions to achieveA new welding method for high-performance electrical fusion, suitable for same or different metals.Method of conductor welding.

Heat-fusion welding requires the use of special molds.

Molds are made ofProcessed from special graphite materials, capable of withstanding the extreme high temperatures during metal melting.

Molds are composed of several parts, including mold cavities, mold cores, and injection holes, and can be processed into various connection styles such as straight, T-shaped, and cross-shaped. The shape, size of the mold cores, and the flow of molten metal are all meticulously designed and processed. The finished connection heads are aesthetically pleasing and uniform in appearance, with a quality that is unmatched by other connection methods.

Heat-fused connection heads upon completion, featuring the following characteristics:

1. The connection points are molecular bonds, without any contact surfaces, let alone mechanical pressure, hence no relaxation or corrosion.

2. Features a larger heat dissipation area, thus having the same current carrying capacity as conductors.

3. Melting point identical to conductor, thus capable of withstanding high repetitive current surges (during faults) without breaking.

Advantages of heat-fusion jointing in construction

Convenient to carry, no external heat source required, suitable for on-site welding in outdoor and indoor environments.

2. Quick welding speed, saving on labor and materials.

3. Simple fusion method, easy to operate, no need for skilled welders.

4. Connector heads are aesthetically pleasing and uniform, with quality easily controlled.

Technical requirements and precautions for heat melting joints

Factors Affecting Welding Performance

A good connector should have a smooth and shiny surface without any pores. Upon cutting and examining the cross-section, it should appear as a solid piece with no pores or defects. The main factors affecting the welding effect are moisture or water vapor. Since both the mold and the conductors to be welded can absorb moisture, removing moisture is an essential step during welding. Another factor influencing the welding effect is the cleanliness of the mold and the conductors to be welded. Dust, grease, oxides (rust), or other attachments on the surface of the conductors to be welded must be completely removed to ensure they are clean and shiny before welding. Otherwise, the conductivity and mechanical properties of the焊接 joint will be affected. If the residue in the mold is not completely removed, it will cause the surface of the connector to be uneven and lack luster.。
