Simple thermo-elastic–plastic models for welding distortion simulation

This paper gives a bibliographical review of the finite element methods (FEMs) applied to the analysis and simulation of welding processes. The bibliography at the end of the paper contains references to papers, conference proceedings and theses/dissertations on the subject that were published between 1976 and 1996. The following topics are included: modelling of welding processes in general, modelling of specific welding processes, influence of geometrical parameters, heat transfer and fluid flow in welds, residual stresses and deformation in welds, fracture mechanics and welding, fatigue of welded structures, destructive and nondestructive evaluation of weldments and cracks, welded tubular joints, pipes and pressure vessels/components, and welds in plates and other structures/components.

Finite element analysis and simulation of welding: a bibliography (1976 - 1996)

Analysis of welding distortion due to narrow-gap welding of upper port plug

A study on port plug distortion caused by narrow gap combined GTAW & SMAW and Electron Beam Welding

Computational analysis of welding radial deformation of typical pressure cylindrical shell with ring stiffener

A fast and simple method for the determination of the residual deformation for a class of welding problems: ring-stiffened pipes, is proposed. The method can predict radial as well as angular distortion of the thin-walled pipe - ring-stiffener/flange assembly. The pipe and stiffener material is elasto-plastic. In particular, the accumulation of deformation in multi-pass welding is incorporated in the model. Each weld pass is treated separately. This facilitates the assessment of the influence of the sequence in which the weld passes are deposited on the residual deformation state. The method will be included in a conversational knowledge bases "expert" system for the production of a welded ring-stiffened pipe.
