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.

Review on finite element analysis of welding deformation and residual stress
TL;DR: In this paper, the influence of welding process, constraints, solid phase transformation and multi-pass welding on deformation and residual stress was discussed, and computation accuracy and efficiency were summarised.

Prediction of Distortion Produced on Welded Structures during Assembly Using Inherent Deformation and Interface Element
TL;DR: In this paper, a finite element method for predicting distortions of structures under welding assembly is proposed, where the distortion produced by various thermal processes, such as the cutting, the forming, the welding and the straightening can be considered.

Fundamental Study on Buckling of Thin Steel Plate due to Bead-Welding
M. Watanabe,K. Satoh +1 more
TL;DR: In this paper, the authors studied on two fundamental problems for buckling of bead-on plate, that is to say, minimum half-wave length, below which a plate does not buckle, and maximum radius of curveture after buckling.

Procedural influences on non-linear distortions in welded thin plate fabrication
TL;DR: In this paper, the effects of welding and related fabrication processes on buckling instability were investigated and the results showed that minor variations in fabrication procedures, including spot and tack welding, have a significant effect on the initial out-of-plane distortion leading to differences in distortion of the post-welded structures.
