| چکیده | ||
| In this paper, the effects of modeling parameters on the temperature field and residual stresses of butt-welded stainless steel pipes were investigated by using finite element modeling in ABAQUS code. The investigated parameters included, heat flux distribution, latent heat, and heat flux type. The birth and death techniques were utilized to consider mass addition from Y308L filler metal into the weld pool. The moving heat source and convection heat transfer were also modeled by a user subroutine DFLUX and FILM in ABAQUS code. In this work, for verification of FE modeling the temperature fields and residual stresses were compared with available experimental results. The simulation results showed that heat flux with a double ellipsoidal distribution proposed by Goldak associated with latent heat parameter and employed a fully volumetric arc heat input, representing the best match with the experimental data. | ||
