High-Temperature Brazing
High-temperature brazing is a joining process that takes place in a vacuum furnace or controlled atmosphere at above 900°C to create high-strength bonds with good corrosion- and oxidation resistance.
The bonding material is a specially formulated metal powder called a brazing filler metal. This filler metal, usually applied as paste in predefined locations on the parts to be brazed, melts during brazing. The molten metal completely fills the narrow space between the parts to be brazed, which remain solid throughout the brazing process. After cooling, the result is a strong metallurgical bond.
