Brazing bar manufacturer: Basic knowledge of brazing bar

　　Brazing strip manufacturerIntroduction,Brazing rod is an important material for the brazing process. Brazing is a welding method, which uses a brazing material with a melting point lower than that of the base metal to be heated to melt, but the heating temperature is lower than the melting point of the base metal, and then the melted brazing material is used to fill the weld, wet the base metal and diffuse with the base metal to form a whole.

According to the different melting point of the solder, brazing can be divided into brazing and soldering. When brazing, the oxide film and oil on the contact surface of the base metal should be removed first, so as to facilitate the capillary to play a role after the melting of the brazing material and increase the wettability and capillary fluidity of the brazing material. The brazing process usually includes assembling the cleaned workpieces together in a lap joint type, placing the brazing filler metal near or between the joint gaps, then heating the workpiece and the brazing filler metal to a temperature slightly higher than the melting point of the brazing filler metal to melt the brazing filler metal (the workpiece does not melt), and being sucked into and filled between the solid workpiece gaps by capillary action, and the liquid brazing filler metal and the workpiece metal diffuse and dissolve each other to form the brazing joint after condensation.

　　The manufacturer of the brazing strip indicates that,Brazing has many advantages, such as suitable for high strength and high temperature resistance, such as aviation, shipbuilding, vehicle manufacturing, chemical industry and other industries. In these fields, brazing is widely used to join various metal materials, such as aluminum alloy, titanium alloy, nickel alloy and stainless steel, to ensure the quality and durability of parts.

The specific type and properties of the braze rod may vary depending on the material composition, the manufacturing process, and the field of application. For example, the silver brazing strip has good electrical conductivity and thermal conductivity, can better weld copper, iron, nickel and other metal materials, and the welding temperature is low, can protect the mechanical and electrical properties of the welding part.The manufacturer of the brazing strip indicates that,The welding metal color of silver brazing strip is bright and beautiful, and the soldering repair ability is outstanding, which can realize zero bridging weld.
