The invention relates to a novel laser wire filling welding digital twinning process. Comprising the steps of setting basic parameters; the method comprises the following steps: selecting materials, namely a solid Aluminum 6063-T83 material, a liquid Aluminum 6063-T83 material and a welding wire 5183 material; establishing a geometric model; defining a Gaussian body laser heat source and the moving direction and speed thereof; setting a physical field; grid division is carried out, and transient research is added for solving; and analyzing a result. The method is applied to the field of welding, the Aluminum 6063-T83 laser wire filling welding process can be effectively solved, the obtained temperature and stress field results are high in goodness of fit with the reality, the speed and the phase change condition of a welding flow field are obtained, the temperature, the stress and the dynamic evolution rule of the morphology of a molten pool are revealed, welding seam forming can be predicted, and the welding
