electronic ignition exothermic welding is a simple, high-efficiency, high-quality metal joining process, which uses the heat of chemical reaction of metal compounds as a heat source to directly or indirectly heat the work through the superheated (reduced) molten metal, in a special graphite mold A fusion welded joint of a certain shape and size that meets the engineering needs is formed in the cavity. At present, electronic ignition exothermic welding has generally replaced the previous mechanical joining methods between metals.
Classification of raw materials for electronic ignition exothermic welding
- Exothermic flux for copper conductors. It uses the chemical reaction heat of metal compounds as a heat source, and directly or indirectly heats the overheated (reduced) molten metal to form a fusion joint of a certain shape and size in the cavity of a special graphite mold that meets engineering needs. Its chemical reaction formula is expressed as:
3Cu2O +2Al ===== 6Cu + Al2O3+ 2573℃
- Hot flux welding of aluminum conductors, also known as flux-coated welding. The flux-clad welding can not only weld aluminum stranded wires with a cross-sectional area of 3-240 mm 2 , but also weld aluminum busbars with a cross-sectional area of 1000 mm 2 .
Iron-to-iron connection, steel-to-steel connection, and exothermic flux for steel-to-iron connection, such as electronic ignition exothermic welding of rails. The above is the classification of raw materials for electronic ignition exothermic welding.
Advantages and applications of electronic ignition exothermic welding
Advantages of electronic ignition exothermic welding
The current-carrying capacity (melting point) of the welding point is the same as that of the conductor, and it has good electrical conductivity. After testing, the rate of change of the DC resistance ratio before and after welding is close to zero. This is unmatched by any traditional connection method.
Solder joints are molecularly bonded, permanent, and do not age.
Solder joints are as unaffected by corrosion as copper.
Not damaged by high surge currents. Tests have shown that the conductor melts prior to the fusion joint under the impact of a high current for a short period of time.
Easy to operate and simple. No professional required.
The equipment is simple, light, easy to carry and easy to operate.
The quality of welding can be checked from the appearance.
For electronic ignition exothermic welding, no external power or heat source is required.
Compared to traditional mechanical joining processes, electronic ignition exothermic welding is true molecular welding, the conductors are not destroyed and there is no contact surface, the overall effectiveness of the conductor interface is not changed. The above is the advantages of electronic ignition exothermic welding.
Fields of application of electronic ignition exothermic welding
Lightning protection grounding and surge protection.
Electrical equipment grounding engineering treatment.
Petrochemical engineering construction.
Construction of railways, highways and airports.
Intelligent building construction.
Cathodic corrosion protection.
The above is the fields of application of electronic ignition exothermic welding.
