T1 - Influence of heat control on residual stresses in low transformation temperature (LTT) large scale welds N2 - Independent from the interpass temperature residual stresses in longitudinal direction were lower than in transverse direction. This applies for the surface as well as for the bulk of the welds. Residual stresses in the bulk were in general lower compared to stresses found on the surface. Compressive residual stresses as a result of the martensite formation were formed in the bulk weld metal, only. Independent from the LTT filler used high interpass temperatures were beneficial to reduce the stresses mainly in longitudinal direction. Lower interpass temperatures tend to narrow the tensile zone in the weld metal but they also prevent the formation of compressive residual stresses.
