Inter pass Temp. is not the essential variable and as I know there is no such criteria for Max. and minimum inter pass temp. limit. If your test coupon pass required DT ( Tensile Test, Face Bend, Root Bend) , there is no problem

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
