Dear Mr. Rameshkanna,
Note that clause 3.6.1 clearly states independent PQR's may be combined and does not state WPS's can be made from the combination PQR.

Hi
shakin thobias
1. Please refer AWS D1.1 , Part C for performance qualification requirements.
Range of qualifications - pl refer Table 4.10 & 4.11
2. Combination of WPS is allowed as per 3.6.1 This is applicable for both qualified or prequalified WPS.[ Screen shot from 2015 edition as below ]
Also refer OLD AWS interpretation as below [ 1984 edition]Thanks and Regards
Rameshkannan Devaraj
