The thermal shrinkage technique, which uses shrinkage strain and shrinkage zone to calculate welding distortion, is expected as a simple simulation to predict the welding distortion of large weld structures. In previous studies, parametric study was

Tendon Force is an integral value of inherent stress associated with inherent strain, which is the root cause of welding-induced longitudinal residual stress, shrinkage and bending distortion. Also, Tendon Force concept is a very useful tool for esti
