Background

This article will explain how the fusion weld joint can be configured in OPM. FUSION_WELD class already exist in the schemas but there are no end preparations in the schema therefore we can use this class as per requirement. In this example, the Socket weld joint is taken as an example and Fusion weld is divided into FUSION_WELD_MALE and FUSION_WELD_FEMALE ends.

Steps to Accomplish

1. Launch Class Editor and load OpenPlant schema from C:\ProgramData\Bentley\OpenPlantModeler V8i\WorkSpace\OPModeler\schemas.
   
   
2. Now load the OpenPlant_3D schema and supplement it with OpenPlant_3D_Supplement_Modeling and OpenPlant_3D_Supplement_Isometrics_Isoextractor schemas.
   
   
   
   
3. Locate the WELD_VALUE_MAP class in the schema and switch to properties tab.
   
   
4. Select FUSION_WELD property in the list of properties and rename it to FUSION_WELD_FEMALE.
   
   
   
   Note: We already have a Isometric Value Map custom attribute here.
   
   
5. Add a new property with the name FUSION_WELD_MALE.
   
   
   
   
6. Since we are taking the SOCKET_WELD as an example in this case therefore we will copy the custom attributes from Socket weld ends.
   
   
7. Go to SOCKET_WELD_FEMALE property and click on Custom Attributes... button and select Copy.
   
   
   
   Copy all custom attribute except Isometric Value Map since we already have it on FUSION_WELD_FEMALE property.
   
   
   
   
8. Select FUSION_WELD_FEMALE property and paste the attributes.
   
   
   
   
9. Remove all the values from OpenPlant Physical Catalog Value Map custom attribute by right click “Remove Element” except the SWF and then rename it to FWF.
   
   
10. Now copy the Custom attributes from SOCKET_WELD_MALE property as shown below.
    
    
    
    
11. Paste the attributes on FUSION_WELD_MALE property.
    
    
    
    
12. Modify the value in Isometric Value Map from PE to FW.
    
    
13. Now rename SWM to FWM in OpenPlant_Physical_Catalogue_Value_Map and remove the other values.
    
    
14. Save the changes in schema.

Joint Definition

Now we will need to define the FUSION_WELD_JOINT on the joint class.

1. Go to JOINT class.

2. Right click on Joint Type field in OpenPlant_Physical_JointType_Map and select Add Element option.
   
   
   
   Note: Element will be added at the end of this custom attribute therefor you will need to scroll down to bottom to find it. 
   

3. Name the joint as FUSION_WELD_JOINT.
   
   

4. Right click on End Preparation 1 field and select Add Element. You need to add the preparations as shown below:
   
   

5. Now right click on End Preparation 2 field and select Add Element. You need to add the preparations as shown below:
   
   

6. Now add element on Fastener and add FUSION_WELD in it.
   
   

7. Set the ‘Is Fastener Spec Driven’ field to FALSE as shown below.
   
   

8. Save the changes in class editor.

9. You will need to add the entries in the spec with FWM and FWF end conditions.

Verify the Result in OPM & OPIM

1. Open a new model in OPM.

2. Create a new pipeline and place the components with FW end preparations.
   
   
    
   We have added the elbows in the spec with FWF end preparations.

3. You can check the joints in item browser as shown below.

    

4. Create an Iso-sheet and publish i-model.

5. Load the i-model in OPIM and create an Isometric.
   
   

6. Check the welds data in OPIM as shown below.
