How do I check a welding shop’s quality control and rework records?

Quality records are the shop’s memory. Ask what is inspected, by whom and how often, and whether customers or outside inspectors check the work too. Look for signed reports on important jobs and ask how the shop keeps records for work done years ago.

Then read the rework log. A few fixes are normal; the question is whether the shop knows why they happened. Ask for examples of a problem, its cause and the change made afterward. Repeat defects on the same kind of job suggest a training, equipment or process gap. Compare rework hours to the jobs they came from, if the shop tracks them.

Check the people. Ask which welders hold current qualifications and who supervises. Ask whether any customer has withdrawn work or required corrective action, and whether any claim is open. Ask your lawyer about warranty exposure and your insurer about coverage. An honest answer about a past failure is worth more than a spotless claim. If the shop lacks written records, ask how the owner knows work is sound and how mistakes are caught. A shop that relies on one experienced person checking everything may be fine, but you need to know how that knowledge will carry on under new ownership.

Key takeaways

• Request inspection reports, test results and welder qualification records.
• Read the rework log for repeated causes, not just totals.
• Ask about customer rejections, corrective actions and open claims.
