Hi Everybody, Where can i find in ASME standards the minimum girth butt joint to girth butt joint distance for piping?

Hi Everybody, This is my query: I would like to prepare single WPS with two supporting PQRs. PQR-1 is GTAW process with 2.77mm coupon thickness and PQR-2 is SMAW process with 10.00mm coupon thickness. I would like to know if I can make WPS with the PQR-1 as root/hot pass and PQR-2 is fill/cap...

I would like to know where can I find the required maximum hardness test value(HB) of carbon steel(A106-B) after post weld heat treatment. Is this mandatory to carry-out in the preparation of welding procedure, if the design codes are for ASME I, B31.1 and B31.3?

Where can I find in ASME Section I the requirements for the heating and cooling rate during post weld heat treatment of material(ie: Carbon steel)?

As I have seen in AMSE IX, AISI904L material is equivalent to SB677 which is P No.45. I have WPS for SB407 which is also a P No.45, can I use the same WPS for welding of AISI904L material? thank you.

I would like to know the difference of E7018-H4 to E7018. In our WPS it's mentioned the electrode classification to be used is E7018. Can we use E7018-H4 without amending or changing the WPS? Thanks.
