【Summary Description】 Aluminum solder is an irreplaceable Welding materials with excellent properties that cannot be replaced by other solders. The solder has a suitable melting point, excellent diffusion, good manufacturability, good oxidation resistance, and good wettability.
The application field of foreign aluminum alloy is constantly expanding. In addition to the application in aviation, aerospace and construction industries, it is also more and more widely used in automobile, shipbuilding, machinery, electrical appliances, refrigeration, military and packaging industries.aluminum solderIs an irreplaceableWelding materials, has otherSolderUnreplaceable excellent performance, the solder has a suitable melting point, excellent diffusion, good process, good oxidation resistance, good wettability.
With the development of aluminum alloy application, aluminum welding problem becomes more and more important, the application of aluminum alloy and the development of aluminum welding technology are complementary to each other, to expand the scope of application of aluminum alloy, must improve the welding technology of aluminum alloy, especially some new application field of aluminum welding process put forward new requirements.
The application of aluminum solder in the refrigeration industry is also a new development direction. The traditional refrigeration technology uses radiators, and the connecting parts are brazed. The quality of brazing is not easy to guarantee, and the refrigerant is easy to leak. The currently used Freon refrigerant is the culprit that causes the destruction of the atmospheric ozone layer. Therefore, the application of aluminum alloy radiator has a good prospect, which is a major measure in the refrigeration industry, and it has been continuously promoted abroad.
An important problem in aluminum welding is the production of aluminum solder. At present, aluminum solder is divided into two series according to the different base materials of welding. One is the solder used for processing aluminum welding, and the other is the solder used for casting aluminum welding.
In aluminum alloy welding, the choice of aluminum solder varieties should also be standardized. The choice of solder depends first on the base material. There are welding of the same base material and welding of different base materials. No matter what kind of welding, several kinds of solder are available. The purpose of this choice is to depend on the performance requirements of the weld.
