Problems solved by technology

[0004] The defect of the existing technology is: the current welding process design adopts a two-dimensional model, and the process design is completely dependent on the paper two-dimensional diagram that uniquely expresses the design intention. A lot of energy of craftsmen is wasted in the mutual conversion of expression modes, and ambiguity and deviation inevitably appear
[0005] 1) At present, the domestic three-dimensional welding process design is still in the exploratory stage
[0006] 2) During the process design process, the 3D model issued by the design department cannot be directly used to carry out process design
[0007] 3) poor consistency
During process design, it is necessary to convert the 3D model into a 2D graph, resulting in non-unique data sources, which cannot be associated with the product design model
And when the same product is compiled by different technicians, different plans will be obtained, which lacks consistency, and it is difficult to fully and correctly consider the welding process in the initial stage of product design, and the feedback and modification of welding process problems are slow and difficult to achieve
[0008] 4) The process design and process simulation are disconnected, the simulation parameters and process design parameters cannot be automatically transferred, and the workload of repetitive labor is large
[0009] 5) The visual expression of the process cannot be realized, and the operability and ease of welding cannot be evaluated, which brings inconvenience to production
[0010] 6) The rationality of the process can only be verified by the actual welding operation, but there is no means of evaluating whether the process has reached the optimum

Embodiment 2

[0096] This embodiment provides a welding process modeling and process design system based on MBD, which mainly includes: MBD design model definition module, 3D welding BOM structure adjustment module, 3D welding process modeling module, and welding feature construction module based on 3D model 1. Three-dimensional welding technology requires six modules: expression module and output module.

[0097] The MBD design model definition module is responsible for extracting the design BOM from the CAD software to form the initial process BOM structure, extracting the necessary information of the view, PMI, and attributes in the MBD model, and completing the lightweight model, and supporting addition, deletion, modification and query operations on the process BOM.

[0098] The three-dimensional welding process modeling module adopts two methods to establish the solder joint / weld structure: 1. Import the solder joint / weld seam defined in the CAD software (such as figure 2 shown); 2. ...
