Abstract: A process of bonding metal parts to one another to form seamless, hollow metal articles, particularly made from beryllium. Tooling is assembled to the parts, prior to hot pressing, to cause pressure to be applied to selective portions of the parts. The parts, assembled together with the tooling, are then subjected to hot isostatic pressing at a temperature of about 1700° F. to 1750° F., and at a pressure of about 2000 psi to 2500 psi, for around 3 hours. The tooling surrounding the metal parts functions to limit the amount of compression of the parts. Articles formed by this process are particularly useful in space flight applications because they are formed of a homogeneous material. Strength of the bond is enhanced because no filler metal is used. The absence of a filler metal also eliminates any thermal stress problems as a result of differences in coefficients of thermal expansion.

Abstract: A welded bracket for use in repairing a shroud in which one or more shroud girth seam welds have experienced stress corrosion cracking. A plurality of the welded brackets are placed around the outer circumference of the shroud at a plurality of azimuthal positions at the elevation of the top guide support ring. Each bracket is constructed by welding curved plates.

During welding, the elongated dimension is aligned parallel with the length of the weld joint. This combination enables joining of the welded bracket parts with both the initial weld joint preparation and the completed weld having a uniquely thin width and with a high aspect ratio of depth to width. This high aspect ratio reduces the number of weld beads needed to build the weld joint.
