Selection of welding filler metals is a serious engineering process and requires knowledge and experience in material engineering and metallurgy, mechanical design and corrosion engineering (as a minimum). In short, you need to be a welding engineer to know how to select filler metals for any welding application.
In this case, E8018 series would be a general choice but you must consider the chemical composition and select matching filler metal composition (E8018/ER80S filler metals are not the same). Additionally, you need to know your Pre-heat & inter-pass temperatures and PWHT parameters.
These all depend on the case. I recommend you to consult a qualified welding engineer. Doing these kinds of demanding jobs with online Q&A is not a good idea.
