Abstract
Application of electroslag welding in fabrication of shells of turbine penstocks at hydraulic power stations leads to a change in their shape under the effect of residual welding distortions. Given are the calculated dependencies of changes in shape of the shells, allowing for their geometric dimensions and technological factors.
Keywords: electroslag welding, turbine penstocks, shells, residual welding distortions, sag, calculation of changes in shape
