ABSTRACT:
The present invention provides a method and means for maintaining metal parts in fixed relation to each other throughout a brazing cycle. The fixed relation is maintained by supporting the parts on concentric support rings made of the same alloy as the parts. The support rings lie within backup rings which exhibit high creep strength at the temperature necessary to braze the parts. The backup rings are slideably supported on a base, and a cover is provided which cooperates with the base to prevent furnace contaminants from contacting the parts during the brazing cycle.
