The pulsed laser welding technique involves complex physical mechanisms, which demand a multiphysics welding simulation for reliable computational analysis. Although the multi-physics simulation provides high accuracy in detailed welding information, it is difficult to apply in practice, as it requires vast computational resources for systematic analysis. We propose a highly efficient and reliable simulation technique based on multi-physics analysis and mechanical analysis. The developed technique is used to efficiently and reliably simulate a complete model of a nuclear fuel spacer grid by introducing a virtual welding distortion that exports the thermo-mechanical information. This study has the potential to develop the computational analysis and optimization of a sequence of pulse laser welding in a nuclear fuel spacer grid.

“…[9][10][11] Thus, computer methods that perform calculations of the time evolution of thermo-mechanical behavior during welding have already shown great potential for estimating weld residual stress and deformation. However, predictive simulation techniques for weld residual stress and deformation have not yet been established.…”

“…Such an approach is found in descriptions of temperature fields in welding processes [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], as well as in the machining processes [16][17][18][19]. In modelling of temperature field during welding dominate two approaches: analytical [1][2][3][4][5][6] and numerical [7][8][9][10][11][12][13][14][15].…”

Abstract. Analytical model of temporary and residual stresses for butt welding with thorough penetration was described assuming planar section hypothesis and using integral equations of stress equilibrium of the bar and simple Hooke's law. In solution the effect of phase transformations (structure changes and structural strains) has been taken into account. Phase transformations during heating are limited by temperature values at the beginning and at the end of austenitic transformation, depending on chemical composition of steel while the progress of phase transformations during cooling is determined on the basis of TTT-welding diagram. Temperature values at the beginning and at the end of transformation are conditioned by the speed of heating. Kinetics of diffusional transformation is described basing on Johnson-MehlAvrami-Kolmogorov equation, while martensitic transformation, basing on KoistinenMarburger equation. Stresses in elasto-plastic state are determined by iteration, using elastic solutions method with changeable longitudinal modulus of elasticity, conditioned by stress-strain curve. Computations of stress field have been conducted for one-side butt welded of two steel flats made from S235 steel. It has enabled a clear interpretation of influence of temperature field and phase transformation on stresses caused by welding using Submerged Arc Welding (SAW) method.
