Defining Weld Fillet Sets in FKM Analysis Cases

You can define a weld fillet set to join two pieces of metal together in an FKM analysis case.

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 Weld Fillet Sets
  1. From the Durability section of the action bar, click Weld Fillet Set .
  2. Optional: Enter a descriptive Name.
  3. In the Support box, specify the location of the weld fillet set.
  4. From the Weld line filter options, select None to choose the entire location specified in the Support box, or select Specify to refine the location you want to analyze.
  5. Specify the Weld line split angle, which determines how long weld lines with kinks in them are split into separate segments.
  6. From the Structural stress source options, select one of the following:
    OptionDescription
    Auto detect Detects the structural stress source automatically.
    Stress extrapolation Extrapolates stress based on hot spots.
    Stress linearization Determines stress values using the stress linearization technique.
  7. If you chose Auto detect as the Structural stress source, specify a Stress extrapolation threshold as well.
  8. If you chose Stress extrapolation as the Structural stress source, do the following:
    1. Specify the Hotspot type. You can detect hotspots automatically or specify that the hotspots are of type A or type B.
    2. For automatic detection of hotspots, specify the Type A cut-off thickness and the Mesh granularity.
    3. For type A hotspots, specify the Type A thickness and the Reference points.
    4. For type B hotspots, specify the Reference point locations.
  9. Review the default settings of all remaining parameters in the Safety Factors section and in the Static Parameters and Fatigue Parameters tabs, and adjust them as you require. If you change a parameter that the app propagated from the previous FKM assessment, the dialog box flags its field to indicate the edited parameter.

    Important: This guide does not provide any guidance about the specific parameters in a weld fillet set definition. For more information about the parameters in a weld fillet set, refer to your copy of the FKM Guideline. The Weld Fillet Set dialog box identifies each parameter using the same symbols that are used in the FKM Guideline. In addition, the dialog box provides section numbers and table numbers to guide you to the appropriate section in the Guideline.
