Defining Spot Weld Sets

You can define spot weld sets to describe fatigue behavior at the points where two pieces of metal are joined together.

Before you begin: You must have a role that provides access to Verity weld simulations. For the latest information on roles and the apps to which they provide access, see the Program Directory.

About Spot Weld Sets
  1. From the Durability section of the action bar, click Spot Weld Set .
  2. Optional: Enter a descriptive Name.
  3. In the Support box, specify one or more point fastener features.

    You can define spot weld sets for point fasteners whose Construct is Solid hex. For more information, see Defining Point Fasteners.

  4. From the Material options, specify the material definition and behavior for the spot weld set.
    1. Select Use product/model material to use the fatigue properties of the point fastener, or specify that the spot weld set uses Steel or Aluminum weld fatigue properties.
    2. Specify the S-N curve for the weld fatigue.

      For steel weld fatigue behavior, you can specify Mean, Mean -2SD (2.2%), or Mean -3SD (0.12%); for aluminum, you can specify Mean or Mean -2SD (2.2%).

  5. From the Nugget diameter options, select one of the following:
    OptionDescription
    Specify Defines the nugget diameter directly.
    Fastener Defines the nugget diameter to be equal to the diameter of the point fastener.
    Geometry Defines the nugget diameter based on the geometry of the element.
  6. From the l(r) function options, select one of the following:
    OptionDescription
    Displacement control "Structural Joints / Displacement Control" method for defining the function of the bending ratio, r .
    Load control "Small Details / Load Control" method for defining the function of the bending ratio, r .
  7. Click OK.
