This paper deals with experimental data and a predictive method of longitudinal shrinkage and bending distortion which are important in the development of the high accuracy production system of the large welding structures. The longitudinal shrinkage and bending distortion can be calculated from the inherent force, namely Tendon Force, which is related to the total of the inherent strain. First the experimental values of the longitudinal shrinkage, longitudinal bending distortion and the inherent strain were obtained under various welding conditions. Next, the theoretical equation was proposed to calculate the longitudinal shrinkage and bending distortion from the inherent strain. As the results, the validity of the theoretical equation on the longitudinal shrinkage and bending distortion is shown by the comparison between values predicted from inherent force and experimental values.
