Dimensional precision controlling on out-of-plane welding distortion of major structures in fabrication of ultra large container ship with 20000TEU
TL;DR: Based on the welding inherent deformation theory, typical welded joints of two major structures were systematically classified with the different material, thickness, welding condition and joining form; and the relationships between welding heat input and inherent deformations were also presented as mentioned in this paper.

Weld Bead Distortion of Thin-Plate Using Weak Digital Image Correlation Method
TL;DR: In this article, the authors proposed a three-dimensional optical method based on weak digital image correlation technology to track the dynamic distortion of the weld bead throughout the welding and cooling process, which could be useful in the validation of numerical models in the welding process and important to research on welding distortions.

Investigating Welding Distortion of Thin-Plate Stiffened Panel Steel Structures by Means of Thermal Elastic Plastic Finite Element Method
TL;DR: Based on the commercial software MSC. Marc, a thermal elastic plastic FEM with the consideration of material nonlinearity, geometrical nonlinearities, and boundary non-linearity was developed to simulate the welding deformation of large-scale welded structures as mentioned in this paper.
