Resistance brazing is extensively used to permanently join dissimilar materials. The electromechanical equipment production industry relies on this process to join dispersion-strengthened, ceramic composites to metals with high electrical conductivity, such as copper. A fractional factorial experiment was conducted to quantify the effects of the process parameters on the brazement maximum shear strength. Multiple regression analysis of the data was used to develop an empirical model for predicting joint stress from the process control variables. This model provides good agreement with the measured joint strength and clearly indicated an optimal process operating condition.
