Please don't confuse, your welder is qualified to weld 1'' and above outside diameter on groove joint.
-- Other way you can tell 3/4'' NPS and above for groove weld. Outer diameter of 3/4'' is 26.7 mm (more than 1'').
Please check the table QW-452.3 (ASME Sec.IX) for groove weld and for fillet weld you can use him any diameter and thickness
as per QW-452.6 because he have the qualification on groove weld.
