Successful part brazing relies on proper joint design, part cleanliness, and correct fixturing of part assemblies. Routine furnace maintenance allows repeatable, quality brazing results over time. This article describes aluminum brazing processes and process control considerations.

Active metal brazing played a key role in the development and fabrication of a modified beam target for particle-physics experiments conducted by Fermilab. The new target consists of a titanium tube filled with stacked graphite fins that were bonded in place by means of active metal brazing. This article describes the vacuum process and the methods used to evaluate the brazed titanium-graphite joints.
