: The method of using chemical reaction (hot-melt reaction) to produce ultra-high heat to complete the welding. That is to say, the chemical reaction between aluminium and copper oxide (hot melt reaction) produces liquid high temperature copper liquid and alumina residue, and the high temperature produced by hot melt reaction is used to realize a modern welding process of high performance electric fusion.
Hot-melt welding is suitable for electrical connections of copper, steel, iron and ferroalloys of the same or different materials. It does not require any additional energy or power. Usually used in radio and television technology grounding and antenna grounding network construction.
10 advantages of hot melt welding
1. The current carrying capacity (melting point) of the welding joint is equal to that of the conductor.
2. Because the welding joints are welded, they are permanent and will not age.
3. Welding is a permanent molecular bond, which will not loosen.
4. Welding joints are not affected by corrosive products like copper.
5. Welding joints can withstand repeated large surge (fault) currents without degradation.
6. The welding method is simple and the training is easy.
7. The material used for welding is light and easy to carry.
8. No external power or heat source is needed for welding.
9. The quality of welding can be checked from the appearance.
10. 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.
