Abstract
Braze filler in the form of coiled melt spun foil is adhesively bonded to coiled parent sheet metal forming a coiled laminate which can be cut to desired shapes, and brazed as an assembly comprised of laminate and non-laminate parts. Because the parent metal and melt spun foil are cut at the same time, only one piece of material must be handled. The laminate may comprise melt spun foil on one or both sides of the parent metal, may be bonded to the parent metal by means of spraying, rolling, dripping, or brushing, and may be applied to either parent metal or melt spun foil, or both. Application of the adhesive may also be in a pattern rather than covering the entire surface of parent metal.
Claims32
A method for laminating melt spun foil braze filler to parent metal for fabricating brazed assemblies, comprising the steps of
- uncoiling a parent metal starting coil;
- uncoiling at least one melt spun foil starting coil;
- feeding, to an adhesive application system, parent metal obtained by uncoiling said parent metal starting coil;
- feeding, to said adhesive application system, melt spun foil obtained by uncoiling said melt spun foil starting coil;
- applying adhesive with said adhesive application system to a planar surface of said parent metal;
- compressing and bonding with pressure rollers said melt spun foil to said parent metal thereby forming laminated braze clad sheet comprised of said parent metal bonded to at least one melt spun foil;
- coiling said laminated braze clad sheet onto a take up coil;
- forming laminated braze clad components comprised of elements from said laminated braze clad sheet take up coil;
- forming brazed assemblies comprised of said laminated braze clad components and components of said parent metal.
A method for laminating melt spun foil braze filler to parent metal for fabricating brazed assembles, comprising the steps of
- positioning parent metal sheets adjacent melt spun foil sheets;
- applying adhesive to said parent metal sheets;
- positioning said parent metal sheets, including said adhesive, over said melt spun foil sheets;
- bonding said melt spun foil sheets to said parent metal sheets and adhesive;
- forming laminated braze clad sheets comprising said parent metal sheets, said adhesive, and at least one of said melt spun foil sheets;
- forming laminated braze clad components comprised of elements from said laminated braze clad sheets;
- forming brazed assemblies comprised of said laminated braze clad components and components of said parent metal sheets.
A method for fabricating brazed assemblies using melt spun foil laminated to parent metal, comprising the steps of
- applying adhesive to parent metal obtained from a parent metal coil;
- compressing melt spun foil from at least one melt spun foil coil to said parent metal;
- bonding said melt spun foil to said parent metal to produce laminated braze clad sheet;
- storing said laminated braze clad sheet in a take up coil;
- cutting laminated braze clad sheet components from said laminated braze clad sheet take up coil;
- fabricating brazed assemblies comprising laminated braze clad components and optional non-clad components of parent metal without melt spun foil.
A method for fabricating brazed assemblies using melt spun foil laminated to parent metal, comprising the steps of
- applying adhesive to parent metal;
- compressing melt spun foil to parent metal;
- bonding said melt spun foil to said parent metal to produce laminated braze clad sheet;
- cutting laminated braze clad sheet components from said laminated braze clad sheet;
- fabricating brazed assemblies comprising laminated braze clad components and optional non-clad components of parent metal without melt spun foil.
