Weld Log Sheet for Piping Fabrication

A weld log sheet for piping fabrication should be easy for the shop to fill out and easy for QA to audit. The best format is a single standardized table with one row per weld and enough traceability fields to support client turnover and code compliance.

Most fabrication delays happen when data is incomplete: missing welder IDs, ambiguous spool references, or NDT updates stored in separate files. A well-designed weld log sheet reduces this by keeping weld identity, material traceability, and inspection status in one place.

Start with a structured template for consistency across projects, then move to automation as volume increases.

Minimum Fields for Fabrication Teams

• Drawing number and spool reference
• Weld number and weld type
• Pipe size, schedule, and material
• Welder ID and WPS number
• Primary and secondary heat numbers
• NDT method and outcome
• Issue remarks and close-out notes
