Metallographic diagram

Vacuum Brazing Assemble the workpieces to be joined, fill the joints with suitable solder, and heat them in a vacuum environment. After the temperature reaches the liquidus temperature of the solder (not reaching the melting point of the workpiece), the solder melts and fills the joints and generate with the workpiece Diffusion reaction, followed by cooling and solidification, to achieve the effort of joining the workpiece.   Advantages: In a vacuum environment, high-quality finished product without surface oxidation can be obtained, and the deformation of the workpiece is very low. For heterogeneous materials cannot be joined by traditional welding (such as ceramic and melt joining) or difficult to join, can be joined in this way with high bonding strength. Dissimilar metal materials can withstand bending deformation without peeling after being precisely combined.
