This paper presents the development of numerical models which were used to simulate
the behaviour of welded joints containing different combinations of multiple defects under tensile
loads. Four representative combinations of defects were selected (including undercuts, incomplete
root penetration, misalignments…), based on practical experience. In order to create accurate and
functional models, this research involve a number of stages. This paper will focus on the various
improvements made to the models, which started in relatively simple form. For this purpose, initial
experimental and numerical analyses were carried out on specimens made of low-alloyed lowcarbon steel S235, and after their accuracy was verified, the same methodology was applied to
specimens made of higher quality material, steel S275. Improvements made to the models involved
geometry, different combinations of boundary conditions and loads, and some were based on stressstrain states obtained by a combination ...of tensile testing and digital image correlation. The final
result was a set of detailed numerical models which accurately simulated the behaviour of welded
joints with multiple defects in them.
