A method for bonding a coating material to a substrate wherein the properties of the substrate material need to be precisely controlled which comprises providing a substrate which is to be coated, supplying a brazing material adapted to come into contact with and coat at least a part of the substrate, positioning a sheet of coating material distributed in a polytetrafluoroethylene fibrous material in close proximity to said substrate, heating said substrate and coating and brazing materials to a temperature which starts melting of said braze material wherein said heating is done by an induction generator thereby allowing for precisely controlled heating effect, and cooling said substrate, braze and coating material, thereby bonding said coating material to the substrate.
