The yield load values were normalized using the Common Format in order to analyze the effect of the weld, using as reference material C(T) and SE(B) specimens made only of base metal (BM). In undermatched specimens (the weld metal elastic limit is lower than that of BM) the normalized yield load decreases compared to the elastic limit of BM. In overmatched specimens (the weld metal elastic limit is larger than that of BM), the yield load increases. This variation of the yield load depends on the degree of mismatch, and on the relation between weld size and crack length. The numerical results were compared with experimental values obtained with mismatched weld C(T) specimens using an ASTM A 588 steel as base metal.}, number={5}, journal={Revista de Metalurgia}, author={Donoso, J.
