This paper proposes a method to determine the sizes of the standard model which is used in the proposed predicting method of welding residual stress, since the model is necessary for estimating the inherent strain (the source of the residual stress) produced in a joint. In this paper, the method is applied to a butt-welded joint.
Based on the distributions of inherent strain in a butt-welded joint that had been obtained before, it is also shown how to modify them in accordance to the changes of heat input and the kind of steel including the effect of phase transformation.
