Summary:The invention discloses an automobile bent profile welding deformation compensation method and system, and the method comprises the steps: carrying out the welding simulation of automobile sub-assembly data, and determining a position and an out-of-tolerance amount of a size caused by welding deformation; according to the out-of-tolerance position and the out-of-tolerance amount, determining the welding compensation amount needed when a profile is bent, so that profile data obtained after welding compensation is determined; and simulating the bending forming process of the profile data, continuously adjusting the bending forming angle and considering springback compensation, so that the size of the profile data after bending forming is approximate to that of the profile data. According tothe automobile bent profile welding deformation compensation method, the welding deformation compensation problem is considered from the beginning of profile bending forming, so that the size out-of-tolerance caused by weldin
