The research represents the ongoing investigation of the welded joints behavior made
of low-carbon low-alloyed steel in the presence of different multiple defects. Following the initial
experimental and numerical analyses performed on low-grade steel, a set of experiments were
performed with specimens made of steel EN 1.0044 (commercial designation S275JR), along with
development of new numerical models. Four combinations were made, including defects like
undercuts, excess weld metal, misalignment, weld face sagging and incomplete root penetration,
considering that these defects are often encountered in practice, and can appear simultaneously. The finite element method (FEM) was used to simulate the experiments. Tensile properties of the HAZ and weld metal were calculated using strain measurements by the digital image correlation (DIC) method. The finite element method (FEM) results were in good agreement with the experimental ones.
