Numerical Investigation on the Effect of Copper Filler Thickness on the Brazed Residual Stress

Abstract:

In this study, the residual stress in copper base brazed stainless steel plate-fin structure was investigated through thermo-mechanical coupled finite element analysis (FEA) models. The results show that the maximum residual tensile stress occurs in the brazed joint next to the plate side. In addition, the dependence of residual stress distribution on filler thickness was also analyzed. The detailed stress distribution would provide some constructive instructions in the practical brazing procedure.
