Abstract
A method for fabricating metallic structures, especially those having intricate shapes, utilizes a combination of flow forming and bonding. A metal preform having flow forming characteristics is positioned relative to a shaping member and a metal workpiece to be joined to the preform. The preform is heated to a temperature range suitable for flow forming. Pressure is applied to cause the preform to flow form against the shaping member and the workpiece. The preform and workpiece are maintained under coordinated temperature-pressure-time duration conditions to produce metallurgical bonding of the preform to the workpiece.
