QW 200.4 (a)
QW 200.4 (a)
(OP)
I have a questoin for QW200.4(a) of ASME SecIX where we read "one or more processes or precedures may be deleted from a qualified combination procedure".
My WPS:
Base metal thickness:14 mm
process:GTAW
My PQR:
Base metal thickness(Same P-Number and G-Number):20mm
process:GTAW + SMAW
Deposite weld metal thickness:8mm(root and hot pass)
* Other essensial,nonessensial and supplementary variables are same.
*Notch-Toughness test is required.
Now I want to know this PQR support my WPS or not. If answre is "No" why?

The black holes of nature are the most perfect macroscopic objects there are in the universe: the only elements in their construction are our concepts of space and time.
RE: QW 200.4 (a)
Could you tell me about following situation:
1- The same WPS and PQR (if Notch-Toughness test is NOT required).
2-
WPS:
Base metal thickness:16 mm
process:GTAW
PQR:
Base metal thickness(Same P-Number and G-Number):25mm
process:GTAW + SMAW
Deposite weld metal thickness:9 mm(root and hot pass)
**Notch-Toughness test is required
**Other essensial,nonessensial and supplementary variables are same.
Please notice that these promblems are not REAL.
I want to understand the Code(ASME Sec IX) better.It is very good if you bring an example for QW200.4(a)
Thanks again
