Abstract:
A method of facing a substrate comprising the steps of:a) applying a plurality of facing bodies to a carrier in a pattern corresponding to a desired pattern of the bodies on a substrate to be faced, the carrier having holes positioned substantially centrally with respect to each body and each body having, on a contact face thereof to be fixed to said substrate, raised weld elements which serve to locate said contact face substantially parallel and spaced from the substrate; b) applying the carrier to the substrate with said contact faces of the bodies facing the substrate; c) electrically welding each body to the substrate by applying a welding tip to the body exposed through said hole, said weld elements ensuring that a gap remains between said contact face and substrate after welding; and d) brazing said bodies to said substrate so that brazing material flows between said bodies and the substrate.
