Diffusion welding is a welding technique that utilizes the principle of solid-state diffusion to achieve material connection. By diffusing atoms at the contact surface under high temperature and high pressure, metallurgical bonding is formed without the need for filling materials (or only a small amount of intermediate layer), and the joint strength can be close to that of the base material. Its core advantage lies in the ability to weld dissimilar materials (such as metals and ceramics, high-temperature alloys and titanium alloys, etc.), with small welding deformation and uniform joint quality. It is widely used in high-precision manufacturing fields such as aerospace, electronics, and medical.
PRODUCT DESCRIPTION
The process of diffusion welding can be divided into three stages:
Contact stage: Apply pressure to tightly adhere the surface to be welded, eliminate micro gaps, and form physical contact.
Diffusion stage: Under high temperature and sustained pressure, atoms at the contact surface gain energy and infiltrate each other through lattice diffusion, grain boundary diffusion, and other methods.
Combining stage: The diffusion area gradually expands, the interface disappears, and a joint with similar properties to the base material is formed. After cooling, the welding is completed.
