ABSTRACT

The temperature field and the residual stress were obtained using the finite element method (FEM), for a plane plate with a single-pass welding. The length and width of the plates were 250 and 300 [mm] respectively, and three different thicknesses of 6.25, 12.7 and 25.4 [mm] (¼ [in], ½[in] and 1[in]) were considered. The model used was a two dimensional simplification of the three-dimensional actual problem, and the temperature field was calculated using an uncoupled scheme, this means, the temperature was calculated first and then the stress. The effects of different velocities of the arc between 6 and 8 [mm/s], initial temperature (preheat) between 20 and 200 [°C] (72 and 392 [°F]), and thicknesses of the plate were studied regarding mainly about the final distribution and maximum values for the residual stress.
