For Set-on Nozzle,

For Base Metal Thickness consider shell/ reinforcement thickness welded to Nozzle Wall thickness.

For Weld metal Thickness (PWHT calculation) use below.

  For Weldolet connections see below.

According ASME Sec.IX,

Hi

Set In  mostly used for High pressure system it's considered mother pipe thickness only (bevel to be make only mother pipe)WPS and WQT selection to be select mother pipe.

Note if Set On Fillet  weld only applicable,no need to check size and thickness.
