E71T-1M/T-9M (Dual Shield 7100 Ultra)
ALL POSITION – This wire was formulated
with a fast freezing slag
that will support the molten weld puddle out of position. At low (140-200 amps)
they exhibit good gap bridging
characteristics necessary to weld poor fitup. At high amps (200-250 amps) they
exhibit deep root penetration
and can achieve higher out of position deposition rates than stick. This wire
produces low fume generation.
E81T1-Ni2 (Dual Shield 8000 Ni2) HIGH
TOUGHNESS – ALL POSITION – These wires contain 2-3%
nickel. They operate essentially the
same as the E71T-1 all position wires they are derived from. The 2-3%
nickel addition yields CVN toughness
of 40-60 ft.-lbs. at 30-50 ft.-lbs. depending on shielding gas and
cooling rates. Most of these wires will
also maintain 70 ksi min. UTS after stress relief, making them useful
in the vessel fabrication industry.
This wire also meets AWS D.1.1 E8018-C1 chemical requirements for
welding A242 and A588 weathering steels.
