Disclosed herein is a method of making a structure by ultrasonic welding and superplastic forming. The method comprises assembling a plurality of workpieces comprising a first workpiece including a first material having superplastic characteristics; ultrasonically welding the first workpiece to a second workpiece, to form an assembly; heating the assembly to a temperature at which the first material having superplastic characteristics is capable of superplastic deformation, and injecting a fluid between the first workpiece and the second workpiece to form a cavity between the first workpiece and the second workpiece.
