At present, brazing bar technology has been widely used in machinery, motors, instruments, radio and other industries.

Brazing is a method of using a metal material with a lower melting point than the base metal as a brazing filler metal, heating the weldment and the brazing filler metal to a higher melting point and a lower melting temperature than the base metal, wetting the base metal with liquid brazing filler metal, filling the joint gap, and realizing the connection of the weldment. brazing stripTechnologyThe small deformation is suitable for welding complex parts composed of different materials such as honeycomb structural plates, turbine blades, cemented carbide tools, printed circuit boards, etc. Before brazing, the workpiece should be carefully processed and strictly cleaned to remove oil and excessive oxide film, so as to ensure the interface assembly gap,Clearance is usually required0.01To0.1Millimeters.


brazing stripTechnologyNot applicable to the welding of general steel structures and heavy and power components. Mainly used in the manufacture of electrical parts, dissimilar metal components and complex sheet structures, such as sandwich components, honeycomb structures. It is also commonly used for brazing various wire and carbide tools. During brazing, the contact surface of the brazing workpiece is cleaned, and then assembled in the form of overlapping, and the brazing filler metal is placed near the joint gap or directly placed. When the workpiece and the solder are heated to a temperature slightly higher than the melting temperature of the solder, the solder will melt and wet the surface of the weldment,The liquid solder will flow and spread along the joint by capillary action. The braze metal and the braze filler metal thus dissolve and bond to each other to form an alloy layer and, after condensation, to form a braze joint. brazing stripTechnologyThe characteristics of the joint are smooth surface, good air tightness, stable shape and size, the microstructure and performance of the weldment do not change much, and the same or different metals are connected with some non-metals. When brazing, the entire workpiece can be heated, and multiple welds can be welded at one time, which improves productivity. However, the strength of brazed joints is low, and lap joints are often used to improve the strength of the joints by increasing the lap length. In addition, the preparation work before brazing is very demanding. Current brazing stripTechnologyHas been widely used in machinery, motors, instruments, radio and other departments. Brazing is characterized by melting the solder, not melting the weldment. In order to make the brazing part connected firmly and enhance the adhesion of the solder, the solder should be used to remove the oxide on the surface of the solder and the weldment. High brazing filler metal strength, can be used to connect the load bearing parts, a wide range of usesCan be usedSuch as carbide tools, bicycle frames, etc. with solderCompared, The welding strength is low, and it is mainly used for welding weldments that do not bear load but require good sealing performance, such as containers, instrument components, etc. Brazing is widely used in machinery, motor, instrument, radio and other manufacturing industries.

in brazed barTechnologyAn alloy having a melting point lower than that of the base metal is used as the brazing filler metal. When heated, the solder melts and fills and remains in the joint gap by wetting and capillary action, while the base metal is in the solid state, and the brazed joint is formed by interdiffusion between the liquid solder and the solid base metal. brazing stripTechnologyIt has little effect on the physical and chemical properties of the base metal, the welding stress and deformation are small, dissimilar metals with different properties can be welded, multiple welds can be completed at the same time, the appearance of the joint is beautiful and tidy, the equipment is simple, and the production investment is small.
