Re: [MW:17406] WPS

Hi, in my opinion, you can use the WPS for job without impact testing, the minimum thickness qualified changes.

Dear All,

 

Your valuable comment is required on following cases.

 

1. Suppose, if i have a certified PQR for P1 Gr1 to P1Gr1 material with PWHT and impact testing. Process is GTAW and SMAW. Based on this PQR, can I prepare a WPS without impact testing, i.e for materials and design condition doesn't require impact testing. There is no issue in other variables.

2. Is it acceptable to apply a 'WPS prepared and approved for low temperature service with impact testing ' to a job, for which there is no requirement for impact testing.
