Description
Technical Field
The invention belongs to the technical field of groove welding, and particularly relates to a three-dimensional groove inspection welding method based on Smart 3D.
Background
Smart3D can express welding information by two methods, namely physical connection (Physical Connection, PC for short) and free edge processing (Free Edge Treatment, ET for short), wherein: when one part model has topological relation with another part model in a three-dimensional space, generating a PC (personal computer) on a contact surface to indicate that welding information exists; on one face that does not touch other parts (hereinafter referred to as the free edge), the designer manually adds ET as needed to indicate the weld information that the free edge exists. Because the PC is generated according to the topological relation of the model, the PC simultaneously contains the groove information of each of the two parts with the topological relation on the topology face. Since ET is generated from one face on the part model, ET contains only the welding information required for its own associated face.
The welding process design is one of the important points of ship design, and most accidents of hull fracture are caused by welding problems. The groove design is an important link of welding design. The groove is a groove formed in a part to be welded of a weldment and is formed by cutting or naturally assembling angles and is used for containing high-temperature welding melt. The correct groove is beneficial to fixing welding melt and improves welding quality.
The Smart3D traditional welding design method has two ways, namely a property editing method and a two-dimensional simulation method:
and according to the attribute editing method, after PC is selected from Smart3D, a groove design can be performed by clicking an attribute interface. However, since Smart3D does not generate an actual model of the groove, a designer needs to design or examine the opening direction and the groove shape of the groove by parameters in the attribute interface, the base surface used in the part modeling process, and the space imagination. This approach is obviously not intuitive enough, is difficult to design and is prone to error.
Two-dimensional simulation is a groove design method to avoid excessive abstraction. The Korean designs a tool named as Modify Bevel Parameters with preview which is specially used for groove design, and compared with a property editing method, the method has the advantages that the displayed parameters are better associated with a three-dimensional model, but space transformation between a two-dimensional schematic diagram and the three-dimensional model is required to be judged manually, and the function does not support the view of ET.
In view of the above, it is difficult to simultaneously satisfy the requirements of good visibility, high compatibility, rapidness and high efficiency by using the Smart3D software, and thus a new method capable of solving the above problems is needed. The method provides a method for visually inspecting the groove form in a three-dimensional space for welding design. Compared with the traditional design method relying on space imagination, the welding design efficiency and quality are obviously improved.
For this reason, a method for three-dimensionally inspecting a welding groove based on Smart3D implementation is proposed.
