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

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.
