Transient temperature and stress distributions are analytically and experimentally investigated for a butt welded plate of HT36-steel. A two-dimensional thermal FE-model is shown to represent the temperature distribution sufficiently well in a considered case of submerged-arc welding where a high welding speed is used. A two-dimensional mechanical FE-model is used to find the transient stress pattern. The theoretically and experimentally obtained residual stress distributions show some discrepancies which are believed to be due to Bauschinger effects not considered here.
