[MW:10169] Combination of GTAW & SMAW PQR for a WPS.

Dear All,

As per ASME sec 9
PQR 1 - GTAW T - 7.11mm , 1.5 to 14.22mm - A106 Gr.B

PQR 2 - SMAW T - 12.70mm, 5 to 25.4mm - A 106 Gr.B

No PWHT & No toughness.

My doubt is,1) is it possible to combine the above WPS to make GTAW &
SMAW combination.?
If possible wats thickness range.?

2) & Regardless of WPS,
My welder is qualified with Tig Process & Arc Process in seprately,
Is it possible to put them in production for Same A106gr.b material in
combination like Tig root & Arc Filler.
If it not possible. Pl tell me para which restricts this.


Regards
Srinivas
