High-temperature brazing processes have many advantages over other soldering processes as they reduce problems caused by local heating. Parts are heated fully and therefore do not tend to distort.

High-vacuum heating prevents the metal surface from reacting with oxides and nitrides that prevent good joining of the material.

Before the brazing, the components are cleaned and the filler material is applied to the surfaces being joined and then placed in the furnace. High temperature brazing enables the flexibility of joining a wide range of metals, such as nickel-based alloys, stainless steel, and carbon and alloy steel. It is also possible to join non-ferrous alloys based on Cu and Ti.

For optimal soldering results, it is necessary to determine or check:

• the geometry of the base metal taking into account the flatness, roughness, and symmetry
• the surface of the brazed part taking into account roughness values, traces of grinding lines
• the cleaning of parts before applying the filler material
• the filler material
• the selection of the optimal joining cycle, time–temperature

Benefits

• Increased strength of soldered joint
• Increased wettability and flow of the filler material
• Cost-effective process due to the option of simultaneous heat treatment
• Bright surfaces that save expensive cleaning after the soldering
• Repeatable and flexible procedure

Application and materials:

• Aviation, automotive, and energy industry
• Medical, scientific, and general engineering components
• Electronic components
• Brazing of carbide solids to components

Brazing offers the flexibility to join a wide range of metals such as nickel-based alloys, stainless steels, carbon and alloy steels. Non-ferrous alloys based on Cu and Ti can also be brazed.
