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
Regards,
Limesh
