本文讨论了纵向收缩和弯曲变形的实验数据和预测方法，这对于开发大型焊接结构的高精度生产系统非常重要。纵向收缩和弯曲变形可以由固有力即腱力计算出来，它与固有应变的总和有关。首先获得了不同焊接条件下的纵向收缩率、纵向弯曲变形和固有应变的实验值。接下来，提出了根据固有应变计算纵向收缩和弯曲变形的理论方程。结果，通过固有力预测值与实验值的比较，证明了纵向收缩和弯曲变形理论方程的有效性。
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.
