Abstract
PURPOSE: To prevent the deformation to be caused while the welding work, to prevent the crack at the toe of weld, and to uniformize the distribution of the residual stress, by keeping the temperature of the groove covering whole length of weld at 350W450°C until the welding is finished, at the automatic one side welding method.
CONSTITUTION: The generation of the crack at the toe of weld, a large deformation 3, an angular deformation 5, and the residual stress, with the progress of the welding work of the parent metal 1 in the arrowed direction, quickly develops from a point when the temperature of weld zone is cooled down to under 350°C. This fact is due to the Young's modulus quickly reducing at the temperature above 350°C; therefore, the weld zone is heated by the burner, etc., so as to keep the temperature of whole area at 350W450°C, until the welding work is finished; hereby, the plastic deformation due to the shrinking is made easy. According to this method, the generation of the deformation and the residual stress is almost prevented.
