Movie: Diffusion bonding as an outstanding joining technology

10/22/2020

Diffusion bonding allows metal parts to be joined without the use of filler materials. With the help of a close contact between the partners to be joined and a high temperature, the grain growth between the components is stimulated, thus creating a joint-free connection.

The video shows the principle and function of diffusion bonding and demonstrates the advantages of a PVA TePla furnace.

The advantages at a glance:

Very high strengths, which come close to the strength of the base material
Joints are not visible macro- and microscopically: one component is created
No selective corrosion attack at the joint
Large area connections with low material distortion can be realized
Metallically bright components after the joining process
Various material composites possible (e.g. copper to tungsten)
No liquid phase during the entire joining process
