Controlled Atmosphere Brazing

Controlled atmosphere brazing (CAB) is a joining technology that uses a molten filler metal – copper, silver, etc. – to bond two materials. Unlike regular brazing, CAB is conducted in a special atmosphere. This allows the filler metal to solidify and seal a joint without oxidizing.
