Fusion Engineering Device frame seal welder and cutter
The Fusion Engineering Device (FED) is being designed in a torus shape using ten removable segments to form the torus geometry. The torus consists of a frame and ten shield assemblies which fit into the frame. It is necessary to seal the shield segment to the frame for the assembly to sustain an internal vacuum. Designs for the seal, the welder to weld the seal in place, the cutter to remove the seal, and the handling fixture for seal installation and removal are presented. The concept for the seal installation is novel in that precise alignment of the seal to the torus frame and shield assemblies is not required. Vacuum handling technology is used for handling the three story tall, twelve foot wide, fragile, relatively light weight seal. The welder and cutter assemblies track off the seal handling fixture, eliminating the need for complex rails on each of the shield segments. The entire seal installation and removal system has been designed for remote operation.
