For e.g. E 8010-G branded as Shield Arc 70+ by Lincoln electric may be used for this grade or you can use specific electrodes suffixed as P1 intended for pipeline application such as E 8010-P1, better to contact your consumables supplier for available choices.
E8018 C3 may be used if you need impact testing.
PWHT depends on your thickness and the code of construction
Your choice of selection for SMAW is not suitable for a joint where back chipping to sound metal not possible.
Regarding SAW better to contact you r consumable supplier for suitable wire/flux combination, as choice between EA series with 1/2 Mo Vs EM2
