Epoxies Bond Waveguides To Flanges

Abstract

Each waveguide/flange joint made with conductive adhesive and structural adhesive. New two-adhesive joints overcome many of disadvantages of dip-brazed joints, including damage caused by heat of brazing process, corrosion of joints by brazing salts retained in them, cracks in joints, weakening of waveguide material and limitation to use of aluminum alloys, which are only ones dip-brazed. Flange machined slightly oversize and beveled to accommodate structural and conductive adhesives.
