Analysis of weld-bonded dissimilar materials

The aim of the present work is to analyse spot-welded dissimilar material joints. The finite element technique was used for the analysis of the present work. The present work shows that the stresses are more concentrated towards the member that has the lowest melting point in the joint. However, the introduction of an adhesive layer in conjunction with the spot weld nugget resulted in eliminating the stress concentration and strengthening dissimilar material joints.
