Creating Fastening Elements 

This task shows you how to create a fastening element.
A fastening element creates a fastening link between several assembly components.
It is not possible to create two fastening elements at the same location.
 
  • A fastening element can be created between:
    • two assembly components.
    • two adjacent parts to the same assembly component.
  • A fastening element is a fastening activity item. See Assigning an Item.

There are four fastening elements available in Tolerance Analysis of Deformable Assembly:

Spot Welding lets you create a welding link according to Fastening options. See Spot Welding settings.

Riveting lets you create a riveting link according to Fastening options. See Riveting settings.

Bolting lets you create a bolting link according to Fastening options. See Bolting settings.

Spot Gluing lets you create a gluing link according to Fastening options. See Spot Gluing settings.
See also Setting Parameters as Default to instantiate a fastening.
Open the BasicTaaProcess2.CATProcess document.

  1. Click Spot Welding .

  1. Select Plate Two as the first assembly component that will be used to create the spot welding.

    The Spot Welding Definition dialog box appears.

  2. Select Plate One as the second assembly component that will be used to create the spot welding.

  3. Set the Diameter option in the Spot Welding Definition dialog box to 5 mm, the diameter information is not taken into account during the computation, only for visualization.

  1. Select the Fastening Points open body on Plate Two where spots welding will be created.

     
When more than one point is specified, normal directions are computed for each point as  being normal to the first component surface on specified points.
 

  1. Click OK.

    The Spot Welding.7.1 to Spot Welding.7.4 items are created.
