Exothermic Welding Powder

Welding powder is a key material used in exothermic welding processes, primarily through chemical reactions that generate high temperatures to create a strong bond between metals. These products generally exhibit rapid reaction times, stable combustion, high temperatures, and concentrated energy release, enabling durable and reliable molecular-level bonding without the need for an external power source. Welding powder is highly safe and easy to use, making it suitable for grounding and connecting a wide variety of metal conductors. Due to its excellent conductivity, corrosion resistance, and long-term stability, welding powder is widely used in power, lightning protection, communications, and industrial engineering, providing efficient and reliable connections for grounding systems.

Features/Advantages:
1. The reaction temperature is above 2500℃, directly melting the base material to be connected. After cooling in the cavity, a one-piece joint with metal atoms fused together is formed.
2. The product of the welding joint is an integrated copper alloy, which completely encloses the base material and has an outer diameter larger than that of the base material. Its current-carrying capacity,high-temperature resistance, corrosion resistance and tensile strength are all superior to those of the base material.
3. The welding points are cast in the mold cavity, presenting a beautiful and consistent appearance, and are stable and reliable.
4. The construction time required is much shorter than that of metal connection methods such as brazing and argon arc welding, and the construction efficiency is high.
5. The welding process does not emit any harmful waste to the outside, making it healthy and environmentally friendly.
6. The welding quality is less dependent on the operation technique, and the welding method is light, simple and easy to learn and master.
7. It can be used for any connection between the same or different metals such as copper materials, copper alloys, copper-clad steel, zinc-clad steel, steel, and stainless steel.

Sweld Exothermic Welding Powder Features/Advantages:
1.The exothermic welding flux does not contain strong oxidants such as phosphorus and potassium permanganate, and has a high ignition point, which helps to improve the safety of use, transportation and storage.
2.We provide precise weight packaging based on different specifications and connection methods, and are equipped with exothermic welding molds to achieve one weld point per package, thereby enhancing the consistency and qualification rate of welding. Different flux formulas are provided according to the welding of different materials. The composition and proportion of metal elements in the flux are adjusted,and the reaction temperature and speed are controlled to achieve the best welding effect.
3.The flux reaction is stable and thorough, and the splashing of reaction residues is strictly controlled. The welded products are smooth and clean, with very little slag inclusion and extremely low internal porosity.
4.The dimensions of the exothermic welding mold, the reaction chamber, and the liquid metal flow channel have all been meticulously designed to prevent residue and molten copper from splashing during the reaction, ensuring reliable welding results.
