P1 to S1

[3lilaggies]

If I qualify on P1 am I qualified for S1 and vice verse? And where in the ASME code book can this be found?

Procedure or welder qualification?

 

[3lilaggies]

welder

 

[metengr]

For welder qualification S qualifies on P base materials and P qualifies on S base materials - Section IX, 2004 Edition, QW 420.2 bottom of paragraph.

metenger,

is it not the same for procedure?

 

[metengr]

No. The information regarding procedures is in the same paragraph. Qualification of a WPS for P-No materials qualifies for corresponding S-No base materials, however, qualification of a S-No base material does not qualify for a corresponding P-No base material.
