[MW:11244] possibility of skip WQT based on other WQTs

Hi,

I have 3 WPS based on AWS B2.1, Process GTAW.

1. WPS-002 (M43 to M8) – Filler Metal ER 308L (F6)
2. WPS-004 (M43 to unassigned Ni263) - Filler Metal B21B783  and
3. WPS-005 (M8 to M8) – Filler Metal ER 308L (F6)

I would like to carry out WQT on our welders. I have been informed that I can skip WQT on WPS-002 (item 1 above) if a welder is successful on WPS-004 & WPS-005 (item 2 & 3 above). Is this true?

Any explanation and reference to the code? I would appreciate it.

Thank you.
Azril
