Dear Experts
Pls guide me in understanding and coorelate these WPS/PQR Qualification Range/Limitation Requirements
Table 4.1- PQR Qualified in 3G Position ONLY qualified for that position alone
Table 4.5 #27 - Any change in position NOT qualified by Table 4.1 require new PQR qualification for SMAW,FCAW,GMAW,GTAW,SAW
Table 4.6 - A change in position to vertical up. A 3G PQR Vertical Up test qualifies for all position and vertical down.

Question
1) Tables 4.6-(Supplementary Essential Variables requiring CVN) - Does it mean with 3G PQR, literally i can do all positions including 6GR?

These questions often raised by Contractors, QC  & Client Inspectors. Appreciate if all of you can shine some light on this.
Thanks

If your procedures are OTHERWISE QUALIFIED to Clause 4, and all you need is CVN test, then you can run the vertical up for CVN testing and you're covered all positions.

Duke,
I don't agree with you since the table 4.6 specifies supplementary essential variables and thus it always goes with the table 4.5.
Nalla,
The meaning of item 6 of Table 4.6 is that the vertical-up position qualifies for all positions only regarding CVN requirements.
That happens because the vertical-up progression results in worse CVN test values due to higher heat input not only with respect to
vertical-down but also to all other positions and thus if you pass the impact test at vertical-up position you qualifies for all
other positions regarding impact test requirements. A look at this link could help you clearly understand this issue:

Maybe it's just me, but isn't that EXACTLY what Duke said 7 MONTHS ago. 

Why do some organizations think they need to drudge up old threads and pick a disagreement just to post a link to their own website promoting themselves to others?

Duke specifically stated that PQR's needed to be tested to other criteria first and that if CVN's were then required additionally for the job that they could be done with only one test plate from Table 4.6 in the vertical up progression.  When combined with Nalla's question it appears to work together and explain what appears to have been a misunderstanding by Nalla between the Tables and wondering if one was saying the vertical only qualifies for vertical (which it does) but that the other said the vertical qualifies for all positions (which it does but is an entirely different application as the first is for Procedure Qualification and also qualifies the welder for that position in those parameters while the second is only qualifying for CVN's).

Isn't that what this new post is also stating? 

I know I occasionally misunderstand Nalla, but I was pretty sure this one was nailed down.

That answered Nalla's question as I read it and appears to be an accurate statement.  Did I miss something?  I'm probably just tired.  But some things just irk me.  Especially when EVERY post some people put up has a link to promote themselves.  Why must we have a link to go to when a few words already posted answers the question? 

Besides,  I don't go to links unless I know the person and feel they can be trusted in case of viruses and other issues.   I don't know this poster and sure don't trust his motives and/or methods so why should I trust his link?  They won't even give us a name. 

Now, before I blow off too much, their answer appears to be correct also.  But why was it thrown in at this point?  I know, we all add input on occasion some time after conversation has ended.  But saying we disagree with another poster and then stating what appears to be the same idea...  I better just go before John has to chastise me. 

Have a Great Day,  Brent
