Diffusion welding is a kind of pressure welding method in which two closely-welded weldments are held in a vacuum or protective atmosphere after a certain temperature and pressure are maintained, so that the atoms of the contact surface are mutually diffused to complete the welding. This welding method is to achieve the welding of two weldments by mutual diffusion of intermetallic atoms and metal bonding without the participation of a liquid phase or a very small amount of transition liquid phase, and no as-cast state remains in the joint.
Mainly used for metal and metal, metal and glass or ceramic and other non-metallic materials, non-metallic and non-metallic materials between the diffusion welding; diffusion welding is widely used in aerospace, aerospace, marine and other engine blades, falcon, Missiles Fuze, optical components and radar and other components of the processing areas.
