Abstract:     Brazing joints are widely accepted in industry due to its simplicity in a variety of applications. The strength of brazing joints determines the reliability of brazed engineering components. So the need to ascertain the reliability or to predict its failure (without some destructive testing) becomes high. While concrete testing is preferred conceptual testing in the form of computer aided analysis can also be beneficial. In this paper, we have used Finite-Element Analysis software, Abaqus CAE, to investigate a joint combining cemented carbide brazed with silver-based filler metal. In this paper, 2D analysis has been adopted because the thickness of the material (in 2D) does not influence the final calculation results. We have applied constant loading and constant boundary condition to explore data from the elastic and plastic strain analysis through which we were able to predict the maximum joint strength with respect to the joint thickness. The result could be transferable to a real-life field situation. The final results showed that there is an optimum thickness for the filler metal to obtain maximum strength which matched the results achieved through concrete experimentation.
