WebJun 11, 2024 · Brazed joints are widely used to join two metal surfaces without melting the base material, avoiding distortions and microstructural changes [ 1 ]. The principle is using capillarity to introduce melted brazing alloy between two metallic surfaces to be joined. It differs from soldering by heating temperature, higher than 450 °C. WebBrazed joints exhibit their maximum strength when the brazing filler material is stressed in shear, that is in a direction parallel to the surface it covers. Therefore one must avoid any Brazing-joint-design where tensile forces act in perpendicular direction to …
