Nejsem si jistý, jak přeložit "clad", cladding je asi navařování/návar. Zde uvedené věty nenavazují.

As a basic principle it is necessary to ensure that the joint clearances employed in situations other than where a sheet clad with filler material is employed should be bigger than those generally recommended for capillary brazing processes.

Unless the components were moved with respect to each other while the filler metal was molten, the joint would contain a massive amount of entrapped flux and be seriously unsound. Such a result needs to be avoided. For this reason clad sheet, rather than a foil washer, would be a much better option.

The components are assembled such that the clad surface is in intimate contact with plain aluminum at the joint-line so that, on melting, the alloy flows, wets the plain aluminum, and forms the joint.

The cladding is generally of the order of 10% of the overall thickness of the material.
