Abstract: Face sheets are bonded to honeycomb core material by applying brazing material to a side surface of one of said face sheets, placing one side of the honeycomb core material against the side of the aforesaid face sheet covered with brazing material and the other face sheet against the other side of the honeycomb core material, heating the assembly to melt the brazing material, and thereafter permitting the assembly to cool. Capillary action causes flow of the brazing material from the face sheet initially covered therewith to the other face sheet when the brazing material is melted.

Abstract: A thin, perforated, metal sheet, one side of which is to be brazed to another element, has the other side thereof treated to prevent braze alloy from flowing into and through the perforations by spraying said other side of the sheet with a nonrunny or thixotropic braze stop-off compound while at the same time maintaining a gentle flow of air or other gas through the perforations in the sheet in the direction of spray flow so as to carry away particles of spray material which pass through the perforations and thereby prevent such spray particles from contaminating the brazing side of the sheet.
