I would advise to read QW-409.1 and the appendix H in ASME IX.
When impact test is applicable, heat input becomes a supplementary essential variable.
New PQR is required when heat input is increased.
So, considering the calculations of heat input given in QW 409.1 you have to record the max heat input per pass

--I.e Heat Input is different in various layers for the fillup passes.On Sat, 30 Mar 2019 at 18:01, Gowtham Rajendran <rajgowthamiwe@gmail.com> wrote:Hi ,A very good evening to you all.My doubt is in establishing the heat input for multipass welding , (root , fill & cap) , for the fillup passes my parameters are different for different layers , which one should i consider for establishing the Heat Input because in this CVN Requirement apply & the heat input cannot be increased as per the code (Be it ASME Sec IX or AWS D1.1).How to solve this problem? Kindly help.Regards,Gowtham.
