The code does not give you these temperatures.
That's the welding engineer's job. Of course, there are tables and recommendations but not in ASME Sec. IX.
These are "change" in temp, not the temperature itself.

Design Code: ASME B31.3 Welding Code: ASME SEC IX
I have a Low temperature carbon steel impact tested PQR with a PWHT range of 600⁰±10⁰C.Is this condition giving an exemption for me on QW406.3 to prepare a WPS with maximum interpass temperature of 200⁰C.
Maximum interpass temperature observed during specimen welding: 140⁰C
