Title:
SHEET WELDING DEFORMATION MODEL CONSTRUCTION METHOD AND SHEET WELDING DEFORMATION LEVELING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/155295
Kind Code:
A1
Abstract:
A sheet welding deformation model construction method. The method comprises: obtaining material attributes according to a sheet material needing to be leveled, and collecting on-site welding process parameters; and constructing a welding deformation mathematical model according to corresponding data and intrinsic strain theory, and correcting the model by means of actual sampling. Further disclosed is a leveling method. The method comprises: determining a welding deformation type according to a model output, and arranging a corresponding leveling heating wire; using an electromagnetic induction heating method to level a deformed workpiece according to the position of the heating wire; and measuring the flatness of the workpiece after leveling, determining, according to actual requirements, whether a standard is reached, and if the standard is not reached, further performing leveling until leveling reaches the standard. In the methods, the welding deformation mathematical model is constructed on the basis of actual data, so that a reasonable leveling heating wire arrangement can be made while a welding deformation condition can be identified accurately; and a leveling process is pollution-free, reliable and efficient.
