AUDIT CRITERIA FOR FUSION WELDING
1. SCOPE
This checklist is to be ud as a supplement to TPG - AC7110 for suppliers eking fusion welding accreditation. This checklist utilizes TPG - AC7110/12 - Audit Criteria for Welder / Welding Operator Qualification.
2. GENERAL INFORMATION
In completing this asssment, auditors are instructed to respond with a ‘yes’ or ‘no’ to address
kp是啥意思是什么compliance with each statement or requirement. For any negative respon, the auditor must clearly indicate in the NCR if the ‘no’ reflects noncompliance with respect to existence, adequacy, and/or compliance. Existence relates to evidence of a documented procedure or policy, adequacy relates to the completeness of the procedure or policy, and compliance relates to evidence of effective implementation.
All negative respons require a Nonconformance Report (NCR). Not Applicable (N/A) respons do not require an explanation, unless otherwi noted. There is only one plausible reason for an N/A,
which is, that a particular operation or issue is not being ud at the supplier. There are no N/A’s simply for a lack of a customer requirement. If a system is in u, then all questions pertaining to that system are applicable.
The audit results shall not include any customer proprietary information. Technical information on parts which have been designated “Export Controlled – Licen Required” (EC-LR) cannot be input into eAuditNet. If auditors have any questions about this, they should contact the Staff Engineer for directions.
