WPS / PQR
WPS / PQR
(OP)
I need some help. My company wrote a WPS /PQR and preformed the coupons to be tested and they all have passed. but the issue I'm having is the thickness range was wrote wrong on the WPS and the PQR. The welder performed the coupon with a 2" S40 and the range thickness says .088 - .216. My customer wants a .226 thickness range. my question is do i need to have a new coupon done and rewrite the WPS / PQR for this range or can i work of this wps /pqr without changes.

RE: WPS / PQR
If it is Section IX, this is an administrative or editorial error because technically, the PQR qualifies to a thickness of 2X the base metal thickness (0.308").
Go back and amend the PQR deposit thickness range with an editorial note that the maximum thickness qualified was incorrect due to an error, and should be 0.308" based on 2 x the coupon thickness. Once this is completed revise the WPS to reflect the revised PQR, again using an editorial note.
No further action is necessary.
Why? See QW-200.2 in Section IX below
(c) Changes to the PQR. Changes to the PQR are not permitted
except as described below. Editorial corrections or
addenda to the PQR are permitted. An example of an editorial
correction is an incorrect P‐Number, F‐Number, or
A‐Number that was assigned to a particular base metal...
In your case you had the incorrect thickness range.
