Exothermic Welding Products

Exothermic Welding

Exothermic welding, also called hot melt welding, fire-clay welding, thermite welding and explosion welding, is a high-heat principle that utilizes the redox reaction between metals, the operation of which is simple, easy to learn, safe and efficient, and it has significant results in the production of high quality permanent welded joints between homogeneous metals and metals of different materials and is now well known to the public, becoming more popular in more and more architectural designs, and widely required to replace the connection method using conventional metal fixtures.

Exothermic welding requires high-quality graphite to form a cavity mold with a certain shape, such as line style (butt), T-joint (three-way), cross-type joint (four-way) and so on. The mold can be used multiple times, effectively saving costs.

Exothermic Welding Advantanges:

Experiments have shown that the the change rate of DC resistance before and after welding is close to zero, which is incomparable with any traditional connection mode.

Operation flow of hot-melt welding

  1. exothermic jointshould be cleaned, and then the welded conductor should be fixed at the center of the mold cavity.

Exothermic Welding for GroundingPrecautions Flammable and explosive articles shall not be placed within 2 meters of the site during construction operation. Unrelated personnel shall not stay and operators must wear heat insulation gloves and related protective equipment.

As the exothermic welding supplies, our exothermic welding productsis quite good, if you need please contact us.

Origin of new material development

  1. copper clad steel ground wireis a new type of material developed by our Company to replace pure copper. Because it has the advantages of high strength, low price, high corrosion resistance and high conductivity of copper, and meanwhile its comprehensive performance is high and its cost is more economical than pure copper grounding device, it has been widely used in UHV lines, petrochemical industry, nuclear power and high-speed railway, especially in key projects in recent years.
