Influence of the welding sequence on residual stress and distortion of fillet welded structures
TL;DR: In this paper, a sequentially coupled thermo-mechanical finite element model that considers temperature-dependent material properties, high temperature effects and a moving volumetric heat source was used to investigate the effect of welding sequence on the residual stresses and distortions in T-joint welds.

Finite Element Analysis of Welding Distortion in a Large Thin-plate Panel Structure
TL;DR: In this paper, the welding distortion in a large thin-plate panel structure was predicted by means of elastic FEM based on inherent strain theory and interface element formulation, and the influences of welding procedure and assembly sequence on the final distortion were examined numerically.
The effect of welding sequence on panel distortion is evaluated
TL;DR: In this paper, the effect of welding sequence on panel distortion was investigated using the finite element method and the joint rigidity method was found to be effective in determining the optimum welding sequence for minimum panel warping.
