Abstract

The invention discloses a brazing flux solution and application of the brazing flux solution. The brazing flux solution comprises, by weight, 16.0-20.0 parts of brazing flux, 9.5-10.5 parts of brazing flux additives, 1.6-2.0 parts of functional additives, and 68.0-72.4 parts of water. The brazing flux solution can remove volatile oil on the surface of base metal and enhances the brazing filler metal joint filling capacity.

Description

technical field [0001] The invention belongs to the field of brazing, in particular, the invention relates to a brazing solvent and its application. Background technique [0002] Flux spraying is to spray the flux solution evenly on the surface of the welding base metal. The flux solution can remove the oxide film on the surface of the welding base metal, make the solder flow freely, increase the diffusibility and fluidity of the filler metal, and Prevent the surface of parts from being oxidized again during welding. However, the existing flux solutions need to degrease the base metal before use, and have high requirements for parts and components, and the welding qualification rate is low. [0003] Therefore, the existing flux solvent needs to be further improved. Contents of the invention [0004] The present invention aims at solving one of the above technical problems at least to a certain extent or at least providing a useful commercial choice. For this reason, an ...
