Abstract
In this paper a three-dimensional welding simulation was carried out in the FE software ANSYS in order to predict transient temperatures and the residual stresses in a three-pass welded tubular joint structure. The thermal analysis and the moving heat source were verified with temperature measurements, and the computed residual stresses were verified with hole drilling measurements. The calculated and measured temperatures were in good agreement, and the computed residual stresses were in qualitatively good agreement with the experimental results. Residual stress relaxation analyses were carried out with similar load as in earlier fatigue testing on the same tubular joint structure. The FE residual stress relaxation analysis showed a small amount of relaxation early in the fatigue life.
