Abstract: A rotatable welding frame assembly for aligning and welding a number of workpiece components into a single workpiece may include a first frame for supporting one of the workpiece components. The assembly may further include a second frame for supporting another workpiece component. The assembly may further include a pivot interconnecting the first and second frames whereby the second frame can pivot between an open position in which one of the workpiece components can be loaded onto the first frame and another workpiece component can be loaded onto the second frame, and a closed position in which the components are aligned in a predetermined configuration to be welded. The assembly may further include an attachment mechanism associated with the second frame to secure the workpiece component as the second frame pivots from the open to the closed positions.
