Abstract
An apparatus and a method for measuring the temperature of a reactive metallic workpiece sealed within a retort prior to and during diffusion bonding of the workpiece. The apparatus includes temperature measuring instruments disposed adjacent preselected portions of the workpiece within the retort, thermal conducting means connecting the instruments with display devices located outside the retort, conduits coupled with the interior of the retort and with the display devices, each of the conduits including a first end portion communicating the interior of the retort with vacuum generating means and a second end portion including at least one tubular region through which the thermal conducting means pass to connect with the display devices, and means for sealing the first and second end portions to maintain an evacuated state within the retort after a vacuum is applied thereto. The method contemplates measuring the temperature at the preselected portions of the workpiece within the retort while conducting the diffusion bonding process and then using the measured temperatures to control the temperatures applied to and within the retort during subsequent diffusion bonding processes.
