We have ASTM B705 N06625 and B366 N06625 in process modules that need to be welded. The tensile strength of the N06625 grade 1 material is 120 ksi. Please recommend what type of weld rod/filler metal should be used to weld the N06625 grade 1 material.

Though such alloys are not to be messed with, this is readily googled with good confidence, when looking at brochures from reknowned MFR's such as Special Metals, VDM, Haynes;
