Yes, you should use ER347, please refer API 582 (Welding Guidelines for the oild and gas industries)

for Gtaw, either ER321 Or ER347 shall be used but for SMAW only E347 is to be used because if we use E321, there will be loss of Titanium alloying loss in arc stream

Hi,

Please refer Table 5 of ASTM A312-06. It is very clear.
