Diffusion Welding Machine

The machine is used for diffusion welding process. It is a solid state welding process that creates fusion of surfaces to be joined by applying pressure at high temperatures. The welding process may or may not use filler material. If used, they may be in the form of electroplated surfaces. These welders are ideal for joining refractory metals and many other dissimilar metals.

Welding Process
Diffusion welding process is does not comprise microscopic deformation melting or relative motion of the parts. Heat required for melting the parts is commonly obtained by resistance, induction or furnace. Atmosphere and vacuum furnaces are used for welding general metals. But for joining most refractory metals, a protective inert atmosphere is used.

Uses & Applications
There are many different applications of diffusion welding machines. Some of its uses are in:

• Aircraft industry
• Aerospace industry
• Joining refractory metals
• Welding titanium & titanium alloys
• Metallurgical application
