Copper bar welding Guodian products are professionally manufactured

Product Introduction Guodian Tianbang exothermic welding produces liquid high-temperature copper liquid and aluminum oxide residue through the chemical reaction (exothermic reaction) of aluminum and copper oxide, and uses the high temperature generated by the exothermic reaction to achieve high-performance electrical welding. Modern welding technology. This reaction is carried out in a high-temperature resistant graphite mold, and the exothermic reaction process only takes a few seconds to complete. Product advantages
． The current carrying capacity (melting point) of the solder joint is equal to the current carrying capacity of the wire
. Because the solder joints are made by welding, they are permanent and will not age
. Welding is a permanent molecular bond that will not loosen
. The solder joints are not affected by corrosive products like copper
. Welding joints can withstand repeated large surge (fault) currents without degradation
. The welding method is simple and training is easy
． The materials used for welding are very light and easy to carry
． When welding, no external welding power source or heat source is required
. The quality of welding can be checked from the appearance
． It can be used for welding copper, copper alloy, copper-plated steel, various alloy steels including stainless steel and high resistance heating heat source materials.
Product application
, horizontal connection welding of ground network
, connection welding of signal lines and oil and gas pipelines
, connection welding of signal lines and rails
, connection welding with steel bars
, Connection welding of lead wires and wire terminals
, Connection welding of other electrical appliances
Precautions
First, according to the shape and size of the soldering parts, open a suitable mold and configure it accordingly Type of welding powder
, before welding, process the pull parts to remove oil, dirt and oxide layer
, apply sufficient strong heat to the mold
, install the mold and inspect it before pouring it in Solder powder and ignite the reaction
, clean the mold and prepare it for next use
Exothermic welding is a simple, high-efficiency, high-quality metal welding process that uses the chemical reaction heat of metal compounds as a The heat source, through the overheated (reduced) molten metal, direct welding or indirect welding heating work, forms a welding horn of a certain shape and size in the cavity of the special graphite mold that meets the engineering requirements. At present, exothermic welding has generally replaced the previous mechanical welding methods between metals.
