Is it allowed by the AWS D1.1 code to approve multiple WPSs (for partial pernitration weld types) using one PQR for a full penitration weld, assuming all other variables are the same.
Yes, see the extract below. Section 3.12 & 3.13 deals with the prequalified WPS requirements. In essence, a CJP WPS qualifies for any prequalified joint detail.
