ABSTRACT:
A method of producing a fluid-tight seal between a thin, flexible member and a member support including the steps of providing a pair of spaced apart braze material receiving recesses on an external surface of the member support having a combined depth to accommodate excess braze material during the brazing of the member to the support, positioning the member to extend across the recesses and the surface and brazing the member to the surface while maintaining the contact between the braze material and the member. An apparatus using this method to produce a fluid-tight seal for a thin, flexible member comprises a support surface, a pair of excess braze material receiving spaced apart recesses on the surface and having a combined depth for accommodating excess brazing material and a brazing material located between the member and the surface and covering the recesses and an adjacent portion of the support surface.
