What are the characteristics and application characteristics of brazing?

Diamond brazing is a welding method that uses a filler metal (called solder or solder) with a melting point lower than the melting point of the base material (brazed material) to achieve connection between parts by using liquid solder material to wet, spread, and fill the gaps of the base material at a temperature lower than that of the base material and higher than the melting point of the solder material. So what are the characteristics of diamond brazing? Let's learn about it together below.  

(1) The brazing heating temperature is low, the joints are smooth and smooth, the structure and mechanical properties change little, the deformation is small, and the workpiece size is accurate.  

(2) Different metals can be welded or different materials can be welded, and there is no strict requirement for the difference in workpiece thickness. Brazing diamond tools

(3) Some brazing methods can weld multiple weldments and joints at the same time, which has a very high productivity.  

(4) Brazing equipment is simple and production investment costs are small.  

(5) The joint strength is low, the heat resistance is poor, and the pre-weld cleaning requirements are strict, and the price of solder is relatively expensive.  

Application: Brazing is not suitable for welding and jointing of general steel structures and heavy-load and dynamic-loaded mechanical parts. It is mainly used to manufacture instruments, electrical parts, different metal components and complex thin plate structures, such as sandwich components, honeycomb structures, etc., and is also often used to braze various different-line and carbide tools. During brazing, the contact surface of the brazed workpiece is cleaned and assembled in a overlapping form, and the solder is placed near the bonding gap or directly into the bonding gap. When the workpiece is heated together with the solder to a slightly higher melting temperature than the solder, the solder will melt and soak the surface of the weldment. The liquid solder is spread along the seams with the help of capillary action. Therefore, the brazed metal and the brazed material are dissolved and permeated each other to form an alloy layer, and after condensation, a brazed joint is formed.  

The characteristics of brazing are that the joints are smooth, have good airtightness, stable shape and dimensions, and the structure and performance of the welded parts are not very different, and they can connect the same or different metals and some non-metals. During brazing, the overall heating of the workpiece can also be used to weld many welds at one time, which improves productivity. However, the strength of brazing joints is low, and overlap joints are mostly used to increase the overlap length to improve the joint strength; in addition, the preparation work before brazing is relatively high. At present, brazing has been widely used in machinery, motors, instruments, radio and other departments.
