Drafting integration
Welds are integrated to the drafting by two ways: They are automatically generated in the views, section views and section cuts and impacted by the HLR of the assembly. The possibility to set automatically the pattern to the section views is to define. They produce weld annotations as the “Weld Planners” method and will be integrated in the drafting by the same methodology of the “Weld Planners”

Weld Design 1 – V5R11 Assessment
Product overview & positioning reminder Purpose/scope of the product
Weld Design 1 completes the fabrication and assembly process for industrial machinery by providing a dedicated tool for weld creation, part preparation, and making relevant annotations. The ability to create welds in the 3D digital mock-up facilitates process integration by allowing the designer to manage digital pre-assembly, mass inertia, space reservation, and drafting annotation.

Dashed Weld
Create a weld as several identical beads between two products according to: The count of beads The length of each bead The weld’s trimming lengths The preparation propagation

User Weld
The user can create his own weld. The user creates the shape of the weld bead in a part (any kind of geometry), and a weld annotation in the assembly (and optionally assembly features to handle preparation) . The designer creates a user weld to integrate this shape and the annotation in the weld model and the weld report : this kind of weld is manageable as any “native” weld.

Space Analysis and KWE integration
Mass & inertia calculation: The mass and the inertia of the weld ribbons are added to the mass and the inertia of the whole assembly. It is also necessary to define the the weld material. Clash collision Welds will be integrated in the clash collision of the assembly. The way to integrate welds in the computation depends on the geometry integration in the assembly.
