try FCAW, is much less prone to lack of fusion than GMAW

Not understood. PSL 2 is a quality requirement for linepipe. The choice of welding consumable does not have to correspond with PSL 2. What the consumables have to correspond to are the strength requirements, the toughness requirements and the corrosion test requirements appropriate to the application as defined in the project specification (and that may not have toughness or corrosion requirements – which are entirely application dependent). I can understand a restriction on the use of E**10 electrodes for many pipeline applications – but that is an entirely separate matter.

Dear Zenoto,
Please find out if you can use E 8010 G wherein the tensile strength specified in the MTC of electrode is more than 82 ksi which shall meet the requirements for API 5L X70 as per trailing mail.
In case yes, note to be incorporated in WPS that MTC of each lot of electrodes shall be verified for the minimum requirement of 82 ksi ( instead of 80 ksi).
Regards,
Anup
