R-Exothermic welding material Name：R-type hot-melt welding

Introduction
    HD-R heat flux welding is the use of chemical reaction (combustion), the flux generated by high-temperature reduction of metal components and contained within the molten metal conductor so as to achieve the purpose of welding. Welding fast response, high heat, and can effectively transfer to the conductor welding parts, can be in the same metal, different metals, different shapes, different directions and different cross-sectional area between the welding material.
Features
     good mechanical properties: solder joints of non-surface contact, there is no residual stress, as a permanent joint, good mechanical properties such as tensile strength;
     high current load capacity: solder joints with metal conductors for the molecule, solder conductor current carrying capacity equal to, has good electrical conductivity, weld before and after the change in DC resistivity close to zero;
     resistance to repetitive high-current: the melting point solder joint entity with the same conductor can withstand repetitive high current (fault) the impact, the contact no fuse phenomenon;
     corrosion resistance: molecular conductor Junctions closely with copper and covered with protective effects on the joints from the isolated, which had greatly enhanced the corrosion resistance of the conductor;
     construction convenient, safe: welding without external energy, professional equipment and professional operators in the indoor and outdoor are safe for the operation, significant savings in welding time is short construction time;
     controlled soldering temperature: When welding metal conductor according to performance characteristics, can be configured with different reaction temperature, so that more solid and reliable weld.
Applications
    Products are mainly used in lightning protection and surge protection, computer networking, electrical equipment grounding works, railways, highways, petrochemical construction projects.
