UW 16 C (1) states ;
Integral reinforcement is that reinforcement provided in the form of extended or thickened necks, thickened shell plates, forging type inserts, or weld buildup which is an integral part of the shell or nozzle wall and, where required, is attached by full penetration welds. See Fig. UW-16.1 sketches (a), (b), (c), (d), (e), (f-1), (f-2), (f-3), (f-4), (g), (x-1), (y-1), and (z-1) for examples of nozzles with integral reinforcement where the F factor in UG-37(b) may be used.
I am not sure but this option with clarification with AI can be used.
To overcome the concern raised by Sunil, PWHT or similar treatment can be carried out after build up and prior to making butt weld.
Thanks and Regards.
