ABSTRACT:
A process for brazing a metal face sheet to a honeycomb core to form a composite member. A brazing alloy is placed between the face sheet and the core. Rigid thermal insulation is used to press the face sheet against the core while heating the structure with induction heating for a time just sufficient to melt the brazing alloy. The portion being brazed is covered by an inert gas when it is at elevated temperatures. The rapid heating and cooling of the brazing alloy by induction heating joins the face sheet to the core without excessive energy consumption or the need for a complex vacuum system.
