“…Since mesh sensitivity plays one of the key roles in the numerical simulations of a welding process, special attention is devoted to its analysis. In the literature, it is common to check the mesh sensitivity over its refinement on a full (global) model . This method can be very slow for models with a large number of finite elements.…”

“…In the literature, it is common to check the mesh sensitivity over its refinement on a full (global) model. [32][33][34] This method can be very slow for models with a large number of finite elements. Additionally, it is very well-known that in the weld area and its vicinity, the finite element mesh must be very dense so that the large temperature as well as stress and strain gradients can be properly solved.…”

Summary The paper deals with the numerical simulation and experimental investigations of a buried‐arc welding process on a butt‐welded plate sample. In the numerical investigations, the finite element analysis is carried out by applying the element birth and death technique in the thermal analysis, while the mechanical analysis is performed simultaneously in one step to reduce simulation time. The temperature history at two locations is recorded with thermocouples, while residual stresses are measured by using the hole‐drilling stress relaxation method at four points. The heat input efficiency for the buried‐arc welding process is determined by using a parametric analysis. The numerically obtained temperatures and residual stresses correspond very well with the experimental measurements. Furthermore, by using buried‐arc welding, 73% of the weld filler material is saved and 59% of energy, whereas the CO2 emission to the atmosphere is reduced by 83% in comparison with conventional metal active gas welding for a model of the same dimensions.

“…In that sense, Seleš et al [16] and Elmesalamy et al [17] used Abaqus Plug-in Software (AWI) to speed-up the modeling of thermal loads and boundary conditions that greatly reduce the model preparation time. Furthermore, it is well known that the size of finite element meshes has a great influence on the result accuracy and computational time, so that the finite element calculations with refined meshes have to be done several times in a row [18,19] before tackling the numerical simulation of the welding process. This approach is often unsuitable for engineering applications, especially for models with a large number of finite elements, since it consumes too much computational time.…”

A submodeling technique is applied in the framework of this study on a Tjoint fillet weld example in order to check finite element mesh sensitivity as well as to obtain more accurate temperatures, displacements and residual stress fields in the weld and its vicinity where the temperature and stress gradients are very high. The submodeling procedure of the welding process is demonstrated step-by-step. The obtained results of the temperature, residual stress and displacement distributions correspond very well with the experimental measurements and analytical solutions from the literature.
