I'd like to hear some opinions on heat input of FCAW verses SMAW when
welding a 1-1/2" thick reinforcing pad to a 1-1/2" thick rolled and
welded cylinder. Both items are SA516-70. The weld required is a 3/4"
fillet weld, with a min. pre-heat of 200=B0 F. This would be welded with
one welder on each side of the cylinder.
Would one process be more suited to this to avoid an extremely hard
HAZ? My thoughts are that FCAW will put more heat into the material.
Any thoughts on this would be appreciated.
