HL-T: 2010 Welded + Unwelded Material Certification (FKM)
This tutorial guides you through a step-by-step process that covers the certification of both welds and unwelded material in the same calculation.
Note: Currently, unwelded calculations cannot by-pass the weld calculation
workflow.
Before you begin, copy the file(s) used in this tutorial to your
working directory.
- HL-2010\sidedoor_gp.hm
- HL-2010\sidedoor_gp.h3d
Import the Model and Results File
-
From the Home tools, Files tool group, click the Open Model tool.
Figure 1.The Open Model/Results Files dialog opens. - Browse for and select HL-2010\sidedoor_gp.hm as the model file.
- Browse for and select HL-2010\sidedoor_gp.h3d as the result file.
-
Click Apply.

Identify Weld Lines
-
From the Screen tools, click the Mark Weld tool.
Figure 3.
The Mark Weld dialog opens. -
Click Detect.
HL-WC identifies the welds present in the model and highlights them in red.
Once detection is complete, a message stating the number of weld lines identified is displayed.
Figure 4.The weld line browser is updated.

Screen Welds
-
From the Screen tools, click the Inspect tool.
Figure 6.
The Inspect Browser dialog opens. - Select Subcase 1 (Cruise) from the Subcase drop-down menu.
-
Enter a threshold value of 100.
Figure 7. -
Click Inspect.
Once the screening is complete, a dialog will display the number of failed weld lines.
Figure 8. -
Click OK.
The legend on the right side of the modeling window colors failed weld lines in pink.
Figure 9. - Optional:
Click
in the dialog to plot the ratio of the von Mises stress value of an element and the threshold value you provided.
- Exit the Inspect Browser dialog.
Define a Weld Specification
-
From the Setup tools, click the
Specifications tool.
Figure 10.
The Weld Specification dialog opens. - Select FKM from the Regulation drop-down menu.
-
Click Apply.
Parameters are applied to all the weld line evaluation points.
- Click OK.
Review Evaluation Points
-
From the Setup tools, click the
Points tool.
Figure 11.The Evaluation Points dialog opens. -
Select hlw_T2#Frame_left3#Skin from the weld line list.
Note: The Evaluate checkbox should be activated. Any weld lines that are marked as critical in the screening process are automatically selected in the Evaluation Points dialog.
-
Review the classification parameters.
The classification parameters for each weld vary depending on the weld type and the weld regulation selected.
Figure 12. - Review other weld lines at your own discretion then exit the dialog.
Create and Assign a Material
-
From the Setup tools, click the
Material tool.
Figure 13.The Assign Material dialog opens. -
Click
to select all the parts.
- Click the My Material tab.
-
Click
.
A new material named Material2 is created. -
Modify the material parameters.
- Set the Tensile Strength to 690.
- Set the Yield Strength to 360.
- Set the Normal Fatigue Limit to 310
- Set the Shear Fatigue Limit to 180.
- Accept all other default parameters and click Plot & Save.
Figure 14. - Right-click on Material2 and select Add to Assign Material List.
- Return to the Assign Material Data tab.
- For the part Skin, select Material2 from the Material drop-down menu.
-
Accept the default materials and parameters for all other parts.
Figure 15. - Exit the dialog.
Evaluate and View Results
-
From the Run tools, click the Run Analysis tool.
Figure 16.
The Evaluate Welds dialog opens. - Optional: Enter a name for the run.
- Ensure that all three load cases are selected.
- Select Loadcase Comparison for the evaluation method.
-
Select Both Welds and Unwelded for the evaluation
domain.
Figure 17. -
Click Evaluate.
Both the welds and unwelded elements are evaluated.
Figure 18.By default, Max Utilization - Unwelded is contoured.
-
In the Results Explorer, select Top
Layer and Utilization_X from the contour
result drop-down menus and click
.
The selected result type is contoured.

Under the Tag field of the Results Explorer,
click
.
A guide bar appears. - Select elements to tag.
-
Click
on the guide bar.
