Abstract
A diffusion bonding furnace includes a pressure vessel having a top and a chamber. A press penetrates through an opening in the top of the pressure vessel, so that a first end of the press is disposed within the chamber. The opening in the top of the pressure vessel is sealed around the press to prevent leakage when the pressure vessel is at a pressure other than atmospheric pressure. A moveable bolster is secured to the first end of the press and a moveable platen is attached to the moveable bolster.
