Weld Log Setup for ASME B31.3 Projects
Reviewed 13 August 2026 by Piping Tools Limited
A useful project weld log connects the weld identifier to its drawing, joint, welder, procedure, material, and examination records. The exact record set depends on the applicable code edition, jurisdiction, owner requirements, and project quality plan; this guide is not an approved project procedure or engineering advice.
Start by standardizing your sheet structure across all projects. Assign one unique weld ID per joint and keep drawing references consistent with your latest revision status. This avoids duplicate IDs and missing weld history during fabrication turnover.
If your current process is manual, use a standardized template first, then migrate to a drawing-linked workflow. Piping.Tools can suggest weld details from supported drawings, but a qualified person should check them before they become part of the project record.
Suggested Project Weld Log Fields
- Drawing number and revision
- Weld number and spool reference
- Joint type, size, and material
- Welder ID and WPS/WPS reference
- Heat number(s) and lot traceability
- NDT method, date, and result status
- Remarks, hold points, and release status
Source and scope
Refer to the official ASME B31.3 Process Piping standard, the edition adopted for the project, and its project specifications. A qualified engineer or QA/QC authority should decide which records and acceptance criteria apply.
