Detailed Product Description: | Hot welding of aluminum Introduction Heat welding is the use of aluminum oxide and aluminum metal between the heat generated by exothermic reaction of molten metal to heat the metal and the realization of the method of combining. Thermite welding was founded in the late 19th century, when the H. Goldschmidt aluminum and metal oxides can be found in the external heat source to start with exothermic reaction, and can be self-sustaining once the reaction, the reaction of the general formula: Metal oxide + aluminum (powder) → aluminum oxide + metal + heat Mainly for welding aluminum heat welding copper, brass, bronze, copper, copper clad steel, iron, stainless steel, wrought iron, galvanized steel, cast iron and so on. Thermite welding characteristics and advantages # Weld current flow and wire cut-off equal; # Weld is permanent and will not loose or corrosion caused by high resistance; # The same as copper weld, and more resilient than the copper itself, and not the product of corrosion; # Weld to withstand repeated big surge (fault) current without degradation; # Welding operation method is simple, easy to use; # Device lightweight, easy to carry; # Soldering, no external power or heat source; # Will be able to verify from the appearance of the welding quality; # Can be used for welding copper, copper alloys, copper steel, alloy steel, including stainless steel and high resistance of various heating source material. Hot welding of the main points of aluminum One of the factors that welding effect A good solder joint surface full bright, no porosity, slag, cut its profile as a whole after the pore and defect-free. The effect of the welding is the main reason for moisture or water vapor, due to the mold, solder powder and can be welded in both the physical adsorption of water, how to prevent or get rid of water vapor, is the welding of the most important steps must be taken. Another factor is the effect of welding mold and the cleanliness of welded materials, such as the welded surface dust, grease, oxide or other attachments must be removed to make it clean and bright after the welding operation can be conducted, or after welding the conductivity of solder joints and mechanical performance will be affected. If the mold does not completely remove the residues left behind, it will cause solder joint surface is not smooth, not shiny. To sum up, pay attention to key points: 1, get rid of water vapor (available blowtorch baking), 2, cleaning of welding material, 3, cleaning mold 2 solder powder application notes (1), each packet corresponds to a solder powder solder joints, solder powder brands need to correspond with the mold, carefully controlled to be confirmed before use. (2), solder powder factory has been taken for its moisture-proof layers of protection, but suggested that keep to avoid moisture. |
