Hi Nilesh

Is the welding carried out in shop or at site ? 

Normally, 8in dia X70 grade can be welded using SMAW process. you may choose E6010 as root welding & Hot, Fill & Cap  using E8018G. Refer  Pipe welding brochure of any reputable maufacturer of filler wire. 

If you go with GTAW ER80B2 may be selected. 

Hope this helps

In Carbon steel, why do you use Cr-Mo steel consumable. Any specific reasons???
