Dear All,

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
