Diffusion welding
Diffusion welding is a method of joining surfaces to each other without melting and
without deformation. The process is carried out under vacuum or in a protective gas
atmosphere, with the applicationof high pressure and temperature over a relatively long
period of time. Provided that the surfaces are clean, flat and accurately machined, large
areas can be bonded in this way. A disc of tool steel, for example, with integral cooling
passages, can be produced by welding a cover disc to another disc in which the neces-
sary channels have been machined.
welding can be used for many materials, including the joining of different
types of metals and also the bonding of metals to non-metals. However, resultsare often
improved by incorporating an intermediate layer between the two outer different layers.
