Abstract

Realization of brazed joints involves the use of different joining materials. These joints are designed for various industries including the machine building and special industries such as aeronautics through the use of ceramics and metal brazing joints. Due to differences in material properties of brazing, the thermal expansion, different wetting and dispersion, residual stresses can occur in the joint. These residual stresses can be reduced through proper choice of brazing materials, fluxes and brazing temperature.
