Re: [MW:29446] Re: ASME SEC IX Code Issue

In case of impact test requirements it is a supplementary essential variable. So the max. limit in this case is 195degC. Check QW-406.3 and the tables in article II

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

Pls take into account that the Code is not a welding handbook

i want to know were is given asme sec 9 what will be interpass temprature.is there any value given in code for interpass temp it is given only + 55 c but what temperature we can go +55 c preheating temp given in asme sec 8

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
