What is brazing?
Brazing is the joining of two base materials with a filler metal. As defined by the American Welding Society (AWS) brazing temperatures must be below the melting point of the two base materials, and the filler metal must have a liquidus above 450°C (840°F) to flow smoothly into joints. Mostly performed in a furnace with a controlled atmosphere of vacuum, hydrogen, nitrogen-hydrogen, etc., brazing is also done using torch or induction heating.
Brazing does the work for you
When a narrow space exists between two parallel surfaces, molten brazing filler metal is drawn into that space--even against gravity! This phenomenon is known as capillary action.
Advantages of brazing
- Design flexibility: Assemblies of thin sheet materials, different thermal mass, or dissimilar metals are easily joined.
- Metallurgical integrity: Only the brazing filler metal is melted, not the base metal.
- Labor efficiency: Numerous joints and parts can be batched and brazed simultaneously; welding processes only one part at a time.
- Joint integrity: Capillary action produces leak-tight joints.
- Process consistency: Quality control is assured by using predetermined, automatically controlled and documented furnace cycles.
- No clean-up: Parts brazed in controlled atmosphere furnaces emerge clean and oxide free, eliminating post-assembly cleaning.
