The failure paths differ based on whether there is a reinforcing pad, whether the nozzle is inserted or abutting, and whether there is an inward projection. Note that the strength of each path must exceed either the W value or the W#-# associated with that path. Note also that UW-15(b) indicates that no strength calculations for nozzle attachment welds are required for figure 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).

But, for types I, J, K, L, X-2, Y-2, Z-2 weld, CodeCalc will perform the additional weld size calculations per UW-16(d)(1).
