Whether you are qualifying your first WPS or auditing an existing shop, always remember the core principle of ASME welding: That is the legacy of the ASME welding standard.
Parameters that can be changed without re-qualifying the PQR, though the WPS must still be updated (e.g., changing the joint design or welding speed).
Without an approved WPS, no production welding can occur under the .
