Nadcap Audit Checklists: Heat Treatment (AC7102), Welding (AC7110) and Composites (AC7118)
Nadcap audits special processes against detailed checklists from PRI. These preparation checklists cover the common quality system items, then heat treating (AC7102), welding (AC7110) and composites (AC7118), so you can find gaps before the auditor does. Tick items, see your readiness score, and export a status to PDF.
0 of 35 items complete
11 critical items still open - these are the highest-risk gaps.
Common to every Nadcap audit (AC7004 quality system and job audit)
Heat treating (AC7102 and related pyrometry requirements)
Welding (AC7110 and the applicable welding specification)
Composites (AC7118 and the applicable material and process specifications)
This is a preparation aid built from the typical areas Nadcap auditors review, not the official audit checklist. Use the current AC7102, AC7110 and AC7118 checklists from PRI eAuditNet for your merit status. Critical items map to areas where findings are most common, so close them first.

How to use these Nadcap checklists
Start with the common group because every Nadcap audit examines the quality system and a job audit. Then work through the group for your process. Mark an item only when you can show the record, not when you believe it is fine. For each unticked item, write down an owner and a date. Do a mock audit 6 to 8 weeks before the real audit using the official checklist for your commodity, which you can download after you are enrolled in eAuditNet. Review your last audit's findings first, because repeated findings are treated seriously.
- Use the official, current checklist revision for your audit
- Prepare a job audit package in advance
- Check subcontracted and customer-approved sources
- Close all earlier corrective actions with root cause evidence
What a Nadcap audit examines
A Nadcap audit has two parts: the quality system and the special process, usually including a review of one or more jobs from start to finish. Auditors look for objective evidence that the process is controlled, the people are qualified, the equipment is calibrated and the product meets the specification. Findings are written against checklist questions, and you provide a root cause and corrective action within the PRI timelines. Merit approval and its duration depend on how many findings you receive and how you respond. Customers such as primes use Nadcap accreditation to approve suppliers, though they may add their own requirements.
Typical findings by process
In heat treating, pyrometry gaps are the largest category: surveys overdue, thermocouples used beyond their allowed use, and test instruments out of calibration. In welding, expired welder continuity records, missing procedure qualification evidence and uncontrolled filler metal traceability appear often. In composites, material out-time not tracked, freezer excursions without a disposition, and cure thermocouple records that do not match the part appear regularly. Use these as a prompt for your own mock audit, not as a complete list.
Common mistakes
Preparing only the paperwork and not the floor is a mistake: auditors interview operators and observe the process. Another is using an outdated specification revision on the traveler because the ERP routing note was never updated. A third is poor root cause analysis in the response, which can lead to repeat findings. Keep specification revision, calibration and training data in a system where an auditor's question can be answered in minutes.
Frequently Asked Questions
Which Nadcap checklist applies to heat treating?
AC7102 is the Nadcap audit criteria for heat treating, used with the AC7004 quality system checklist. It references pyrometry requirements such as AMS2750 and the customer or material heat treat specifications.
Where do I get the official Nadcap checklists?
PRI publishes them, and accredited or applying suppliers access them through eAuditNet. Always use the revision that applies on your audit date, as checklists are updated periodically.
How long does Nadcap merit last?
Merit duration depends on your audit results and history, commonly 12 months for new or higher finding counts and longer for strong performers. Check the current PRI rules for your commodity.
Can one checklist cover all special processes?
No. Each special process has its own checklist, plus the common quality system questions. A shop that does heat treat and welding will be audited against each applicable checklist.
Netray builds private AI over ERP and quality records on your own servers, so a question like which furnace surveys are due in the next 60 days can be answered without sending data outside your network.
