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.

[ We claim:] [1.] A method for induction brazing of honeycomb panels, comprising the steps of:(a) assembling a retort having at least three sheets of susceptors sandwiching a workpiece to define two pressure zones divided by a diaphragm;(b) sealing the susceptor sheets;(c) positioning the sealed retort in an induction heating workcell;(d) heating the workpiece in the workcell to a brazing temperature by heating the susceptor sheets with induction;(e) controlling a net tooling pressure in the pressure zones on either side of the diaphragm to avoid core crush of honeycomb core in the workpiece.
