When the importance of producing a perfect brazed joint is uppermost, vacuum brazing is a highly effective method of joining two parts. Due to the nature of the vacuum, heat is evenly distributed and part production is consistent. Brazing requires three components: two parent metal pieces and a filler to join them. In the furnace, the components are arranged so that the filler will melt and flow on the base pieces, and join them solidly when cooled. Vacuum brazing provides strength, durability, and reliability unmatched by other metal joining methods. It also requires no secondary fabrication or finishing.
