چکیده مقاله
This paper reports the finite element modeling of the electric arc welding process for the assessment of the resultant residual stresses for two specific geometries The simulation procedure was first carried out for a Butt Weld geometry for which two different methods, i e the heat flux input and the prescribed temperature, were used to obtain the temperature field The obtained results were compared and the accuracy of these two methods was investigated Next, the method of prescribedtemperature was used to obtain the temperature field induced by arc welding in a Tjoint fillet weld and, conducting a thermo elasto plastic analysis, the residual stress distribution and distortions were computed To simulate the effect of addition of the filler material during welding, the element birth technique was used The results obtained for these two geometries were compared with similar results reported in the literature
