Abstract
An induction brazing uses a multisheet, diaphagm retort having isolated pressure zones to control the net tooling pressure at a level that avoids core crush. The isolated chambers in the multisheet diaphragm allow us to apply controlled pressure to the braze joint, especially at the elevated brazing temperature where the honeycomb core is soft and malleable.
