Abstract:
The method of brazing two pieces of material together with brazing material, comprising the steps of:sandwiching the brazing material between the two pieces of material to define a seam between said two pieces of material, said seam extending in a closed loop about the periphery of said two pieces; holding the two pieces of material and said brazing material in said sandwiched relationship; applying a covering seal about the periphery of the seam, said covering seal being wider in dimension than the thickness of said seam; compressing said seal against said seam to place said seal in compression and maintaining said compression to define an edge sealed sandwich assembly; heating said edge sealed sandwich assembly to the brazing temperature of said brazing material for a predetermined interval to change the brazing material to a molten state; withdrawing heat from said edge sealed sandwich assembly, whereby said edge sealed sandwich assembly falls below said brazing temperature, wherein said brazing material re-solidifies and bonds to the adjoining pieces to form a braze joint; decompressing and removing said covering seal, whereby said pieces are brazed together in a unitary assembly.
