Application

Vacuum diffusion welding technology is a kind of welding method, which is carried out in vacuum, and the weldments are closely bonded. Under the appropriate temperature and pressure (workpiece bonding pressure), it is maintained for a period of time, so that the atoms between the contact surfaces are diffused, so as to form a connection. Vacuum diffusion technology can be used for welding of dissimilar metals, ceramic / metal dissimilar materials, etc.
