Weld Templates

The default parameters shown in the Points tool related to Evaluation Distance, General, and Location Properties can be automatically updated using a weld template file (.xml).

The weld templates are sourced into the HyperLife Weld Certification session via the Weld Template folder. The default location defined in Preferences is: C:/Users/<user id>/Documents/Fatigue/WeldTemplates.

The .xml file placed in the weld template directory is automatically sourced into the session. The weld categories are listed in the Specifications and Points tools.

Apply Weld Templates in Specifications Tool

  1. Select the Regulation.
  2. Click to show weld templates.
  3. Select the weld category for the required type.

    The template names for the weld type are listed from the weld template .xml saved in the Weld template directory.

  4. Select an Evaluation Method and click Apply.

Define Weld Template XML

The weld template .xml should be contained within the <WeldPropertyTemplateData> root tag, as shown below. The tag has one attribute: version.
<WeldPropertyTemplateData version="21.000000">….
….
</WeldPropertyTemplateData>
The weld template should hold at least one <Regulation> root tag, as shown below.
<Regulation name="dvs1608">….
….
</Regulation>
Supported regulations:
Table 1. Supported Regulations
Attribute Valid Values
<Regulation name = “xxxxxx”> dvs1608

dvs1612

eurocode3

fkm
Note: Multiple regulation templates can be saved to a single weld template .xml.
Each weld template based on the regulation and evaluation method is defined by three tables within the <WeldData> root tag, as shown below.
<WeldData Template_name="T_Example" Weld_type="T" >

 <Table type="Evaluation_distance_table" Evaluation_Distance="Auto" Evaluation_Approach="Nominal">

Effective Thickness (Ar) Effective Thickness (Ar) calclated at each location.
Note: The values for each location table attribute are based on the number of locations of the weld type. In the table above, Notch Class – Transverse shows 7 values for a T weld, which are Location1 – 6 from the weld centroid and an additional location for Location_WeldEnd.
If any of these values are to be kept unchanged when applying weld template, the value x should be used. Example: <Column label="Notch Class - Transverse">x F2 F2 F2 F2 F2 F2 F2</Column>

Where, Location1 will retain the default value applied by HyperLife Weld Certification.
