RE: GMAW short circuit process as per ASME section ix

QW-404.32 For the low voltage short‐circuiting type
of gas metal‐arc process when the deposited weld metal
thickness is less than 1/2 in. (13 mm), an increase in deposited
weld metal thickness beyond 1.1 times that of the
qualification test deposited weld metal thickness. For
weld metal thicknesses of 1/2 in. (13 mm) and greater,
use Table QW-451.1, Table QW-451.2, or Tables
QW-452.1(a) and QW-452.1(b), as applicable.

RE: GMAW short circuit process as per ASME section ix

You seem to be mixing diameters and weld metal thickness. 2-7/8" is the minimum diameter a welder would be qualified for if the coupon was 10" pipe.
Weld metal would be unlimited as stated in QW-404.32, which refers you to table QW-452.1(b)

RE: GMAW short circuit process as per ASME section ix

(OP)
YES .
THANKS.
