AWS D1.1 Table 4.5 # 31- Qualification Range & Limitation
(OP)
Dear Sir
Presently I have qualified PQR with Single V welded in 3G Position
Undergone all reqd mechanical test including Impact Test at -20 deg celcius succesfully.
Base Mat- ABS Grade EH36 x 25.4mm Thk.
Filler Metal used - Kobelco LB52-E7016.
QUERY:-
Based on Table AWS D1.1-Ed 2008-4.5 # 31-
1st part "A change in groove type, ie Single-V to Double-V- straigthway -Require - New PQR for SMAW,SAW,GMAW.FCAW,GTAW to be qualified.
2nd Part - But on the same token it states that " Any CJP groove qualifies for any groove detail conforming with the requirements of 3.12 or 3.13"
Based on this 2nd part, can i write new WPS conforming to 3.12 & 3.13 Joint Type/Groove using PQR qualified with Impact Testing?
Can you pls elaborate for better understanding?

RE: AWS D1.1 Table 4.5 # 31- Qualification Range & Limitation
Yes. But you may want to consider adding an addendum of some type which includes your new joint design to your existing WPS rather than creating a new one.
The first part of 3.13 refers you to Figure 3.4. As long as your new Joint Type/Groove design is one of those found in Figure 3.4, including all applicable dimensions, your original PQR also qualifies you to weld any of these other joint types.
RE: AWS D1.1 Table 4.5 # 31- Qualification Range & Limitation
That means I can include all joint type/groove with given joint types and grooves detail in ONE WPS attached with qulaified PQR ( with/without CVN Test Results .
Based on newly prepared WPS complying to essential and supplementary variables(if CVN reqd) to weld all joints with given groove deatails in 3.3 & 3.4
Am i right?
Thanks
