ASME VIII code does not provide such provision. Further, this type of joint is mainly provided for item in cyclic service (mainly by Licensor) to avoid the peak stresses at the nozzle to shell junction.
If weld buildup is used, that junction area is already having residual stresses, further the grain orientation which we obtain through the forged saddle type nozzle can not be achieved by weld buildup.
In my opinion, it has to be forged construction only. Members may please further share their experience.

Subject: [MW:6580] Nozzle weld as per UW16.1 figure f-4 (weld metal build up)
When a lip type joint is specified as per ASME Sec VIII div 1, UW16.1 figure f-4 (as below), can the lip be made with weld metal buildup?
