Morning,

Has anybody a link or clear statement regarding range of qualifications for ASME IX i.e Dia and thickness of pipes covered in regard to carrying out a new WPQR. Hope that makes sense.

Cheers

Table QW-451.1 gives you a variety of thicknesses (parent metal and deposited weld metal)
Do not worry about diameter, it is a non-essential variable.

Deano,
When someone takes the time to respond to your question it is polite to reply,

Regards,

BB in 15614-1 in regards to procedure qualification it states somewhere that one weld position covers all in regards to materials that do not under go hardness testing i.e austenitic stainless steel, is this the case also for ASME IX?

That is the case with ASME for all materials.
Plate or pipe, flat or overhead - all OK.
I have spent over 30 years working with ASME and when I am very unlucky I have to work with 15614-1 and 9606-1.

Change of position is a supplementary essential variable according to ASME IX for SMAW, GMAW & GTAW processes.

QW-405.2
A change from any position to the vertical position uphill progression.
Vertical‐uphill progression (e.g., 3G, 5G, or 6G position) qualifies for all positions.
In uphill progression, a change from stringer bead to weave bead.
This variable does not apply when a WPS is qualified with a PWHT above the upper transformation temperature or when an austenitic material is solution
annealed after welding.

Supplementary essential variables become additional essential variables in situations where procedure qualifications require toughness testing, not hardness testing.

Therefore in summary, if no toughness testing is required, then one position qualifies for all.
