How to create a WPS from a PQR
This article contains the screenshots and the explanation for creating a WPS from a single PQR for ASME IX. The steps and fields will differ for AWS D1.1 and ISO 15614-1, but the workflow will be similar.
To create a welding procedure specification or WPS, select the WPS & PQR main menu and click on the "Create WPS" sub-menu. Then select the option "Create WPS from a PQR" for the "Select WPS Type" dropdown box. Then select the standard and the unit.
Create WPS from a PQR
After you click proceed, a pop up window like the one shown below will display the matching PQRs. Only the PQRs with the status "Approved" will be shown here. Click on the create button to populate the PQR template with the values from the pWPS.
Creating WPS from a PQR - step 2
Enter the WPS number
The PQR data will be processed and the values for certain fields will be calculated as range for the WPS. Once the data is processed, you will see this WPS template.
Creating a WPS from a PQR - step 3
- In the "Qualification Details" section enter a number for the WPS, revision and date. These fields are mandatory;
- You will see the details of the PQR that has been used to create this WPS;
- You may change the customer specification and if the PQR had a specification document uploaded you may change it. These fields are optional;
- You may select or change a customer;
Joint details and joint design
The data from the PQR will be processed in accordance with the code rules and the calculated data will be displayed in the WPS template.
Creating a WPS from a PQR - joint details
- The joint type range qualified data will be displayed here;
- The joint design and other fields will be copied across;
- The calculated values will be shown as range here. You may edit these and set new values within the permissible range;
- If the values shown in a field have one or more options like for backing, you may remove one that is not applicable by clicking on the "x";
If a value from PQR cannot be changed in the WPS, the corresponding fields will be disabled in the WPS template. If a field is not applicable, it will be masked with a 'no stopping' symbol shown next to the field label.
The base metals data and the qualified range for the product thickness will be calculated from the PQR and displayed in the WPS template being created.
Creating a WPS from a PQR - base metals and thickness range
- You will not be able to change the alloy, but if the code permits, the product form and certain other data can be changed;
- The option to select dissimilar metals is disabled here, as the radio button for Yes & No cannot be changed;
- You may change the base metal and pick a different one as long as it is within the qualified set of P numbers;
- Here you can see that the PQR joined base metals that were both P number 1. In this row, the range qualified value for P numbers is "between the assigned P numbers," which is 1 and 1. For material 1, you may pick a different base metal from P number 1. For material 2, if there is more than one qualified P number, you may remove the ones that are not being specified in the WPS;
- The calculated values for thickness and diameter will be shown as range here. You may edit these and set new values within the permissible range;
Your choices for PWHT, impact testing and hardness tests in the scope section of the PQR will be displayed here. These cannot be edited.

The data from the PQR will be calculated and copied to the WPS template being created. You may edit some of the data.
Creating WPS from a PQR - process variables
- All the values shown here are copied or calculated from the data entered in the PQR;
- Click on the relevant tab for the process and other welding data to view the details;

- Some of the data will be stored for each pass;
- Click on the relevant tab for the pass to see and make changes to the data;
In WeldTrace, the approval of a WPS is a two-step process. Once the WPS template is filled out, the person preparing the WPS can recommend its approval and submit it. The same person or another user will be able to see the status of the WPS, open it and either make changes to it, approve it or reject it.
Creating a WPS from a PQR - recommending approval
- The person preparing the WPS can recommend if the WPS is to be approved. Notes can be left for the person who needs to approve the WPS;
- You may preview the WPS in PDF format;
- Clicking "Save" is to save the WPS and return to edit it at anytime;
- Clicking "Submit" will move the WPS to the final stage of the workflow;

Creating WPS - approval status
- When a WPS is saved, but not submitted for approval, the status column will show "In progress";
- You may click on the eye icon in the info column to see the snippet view with the essential details of the WPS;
- The certificate icon is to view the PDF file. If the WPS is not yet approved, it will bear a watermark indicating the status. An approved WPS will not carry a watermark;
- When a WPS is submitted for approval, the status column will show "Awaiting approval";
Creating a WPS - final approval
- The approval status should be confirmed. It may be changed here. A WPS that is not approved will be rejected;
- By clicking here the WPS form will become editable and changes can be made by the person approving it. If any changes are made, the WPS will be put through the approval process once again;
- Any approval comments can be written here;
- Clicking "Submit" will move the WPS to the "Approved" status and the WPS can be used in projects. The WPS (All) menu will also display the approved WPS;
