Abstract

PURPOSE:To prevent joining defects and buckling in the plate width direction of sheet steels by applying an electric current and upset to join sheet steels while releasing the restraint in the plate width direction along with the progress of welding. CONSTITUTION:A thermal deformation restraining device 5 provided with a restraint control mechanism 4 capable of changing the restraint in the plate width direction by the optional quantity at the optional time is used. Then, the formation of a gap taking place at the butt edges of the sheet steels 2 at the early stage of the welding is prevented and the restraint is reduced or released along with the progress of the welding and further, the current and upset are applied to complete the welding. By this method, the joining defects due to the heat input unevenness are prevented and the buckling in the plate width direction of the sheet steels can be prevented.
