The previous WPS PQR is incorrect. What should I do?
Thread Content
While organizing the company’s welding evaluations recently, I noticed a few oversights in previous work. There were no major issues with the testing procedures and results, but there were errors in the preparation of the documentation. For example, the standard to be applied for pipes and tube sheets should be GB151, yet it was listed as JB4708； Treat the type test of T-joints as a pipe-to-tube sheet assessment ； The weld evaluation covers an incorrect thickness range ； The heat treatment temperature does not match the heat treatment curve ； There are also other errors, such as J427 being written as J407, and 6 for thickness being written as 8, etc. How should these issues be handled properly? (The evaluation is invalid; need to redo it. The boss will definitely not agree.) Please give some advice~~~~~~
It does not affect production; the status quo can be maintained for now. If an external auditor recommends that corrections must be made, then revisions will be necessary, but the previous assessment results can be taken into account, eliminating the need for repeated testing.
If the sample and its report meet the requirements, only the information needs to be modified as specified.
Identify and address issues promptly to avoid being caught off guard during external audits.
For WPS, it can be modified and expanded, as WPS allows for the creation of multiple versions based on PQR, through merging or analysis, etc. However, PQR is a record from the testing phase, and in principle its actual content is not allowed to be changed; of course, typos can be corrected by making the necessary changes manually and signing to confirm them.
