Abstract
Welding-induced distortions are one of the major problems frequently encountered in industry. Different geometrical
and welding process parameters are believed to influence distortions. One of the most common types of distortions frequently
observed in butt-welded plates is angular distortion. In this study, the effect of geometrical parameters on angular
distortions in butt-welded plates has been investigated numerically and experimentally. A comprehensive study has
been performed, and several cases with different plate lengths, widths and thicknesses have been studied. Distortions
have been predicted by three-dimensional thermo-elastic-plastic finite element simulation. The finite element results
have been verified by a series of experimental measurements for temperatures and angular distortions. The results of
this study revealed that plate thickness, length and width influence the magnitude and mode of distortions greatly. The
results revealed that decreasing the plate thickness or increasing the weld length results in higher and nonlinear angular
distortions. Increasing the plate width has an adverse effect and reduces the angular distortion. In addition, the thickness
of the plate has a key role on distortion behavior and can lead to buckling in thin plates.
