WPS / PQR 1

[erichenry]

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.

are your parts compliant to the customer requirements if they're all compliant to your internal spec? That should be one question. Is your customer expecting to take advantage of the looser requirement somewhere else, i.e., are they planning on using this to compensate for something else? The answers to these questions should determine your course of action. On the face of it, your tighter requirement should be need to be changed, unless the customer is expecting a lower price due to a higher test yield, or they are looking for something else.

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

First, and most important was the WPS/PQR qualified under Section IX or some other standard?
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.

Metengr, I'm new to the forum. So I didn't know if they were separated or all joined together. So I posted it in multiple areas, because I wasn't sure which one to post it in.
