Welding optimization method

The invention discloses a welding optimization method, and belongs to the technical field of welding. The method comprises the following steps: determining a metal plate mid-plane model corresponding to each metal plate model; sequentially determining the first welding spots as target welding spots according to a preset welding sequence of the first welding spots; combining the models to obtain a combined welding model; performing surface mesh generation and volume mesh generation on the model to obtain a to-be-simulated model; assigning a value to the thickness of the metal plate middle surface model corresponding to the metal plate model by using the thickness of the metal plate model; performing welding process simulation on the to-be-simulated model after assignment to obtain a welding simulation process; based on a simulation analysis algorithm, simulation analysis is conducted on the welding simulation process of the first welding spots arranged according to the preset welding sequence, and the welding
