Analytical, finite element and experimental analyses of thin butt-welded plates are performed for thermal field, distortions and residual stresses assessment. Existing empirical equations, published in the literature, are revaluated and new relationships are proposed to estimate the distortion and residual stress distributions of thin butt-welded plates. To validate the new developed empirical equations, experimental test results and finite element analyses are used. The validation demonstrates that the developed relationships are in a good agreement with the collected experimental results and finite element analyses, representing common shipyard welding conditions. In addition, different thicknesses of thin plates, weld sequences and weld shapes are tested to validate the accuracy of the new empirical equations.
