Here is what automotive OEM auditors actually check during a CQI-15 assessment:
A documented welding quality policy with a named Responsible Person whose authority is defined in the management system. If welding accountability is distributed across three roles with no single owner, Category 1 starts with a finding.
Approved WPS at every welding station. Version-controlled. Current. An auditor can ask for the WPS used on Job X, Station Y, Shift Z, and if the response takes longer than two minutes, the auditor notes it whether or not the weld itself is sound.
Welder qualification records with proactive expiry tracking. Not a binder that gets updated when the auditor arrives. Digital records that alert the supervisor thirty days before a cert lapses.
Monitoring and measurement evidence that matches what the WPS specifies. If the WPS calls for preheat at 100 degrees C, the auditor wants to see thermal data, not a handwritten guess from three months ago.
Corrective action records with closed-loop evidence. The finding, the root cause, the containment, and the verification must form a single traceable thread.
Here is the reality:
Most suppliers that fail CQI-15 do so because their documentation is trapped in paper files, Excel sheets, or disconnected systems that cannot be retrieved during a live audit. The welding quality is fine. The digital evidence chain is not.
When audit prep turns into a fire drill every time, the problem is not the welds. It is the data pipeline.
