19 Carbon
Steel Submerged Arc Wires Spoolarc
80 AWS Class EL12
Description: n
Low manganese and silicon wire - minimal
rust and mill scale tolerance. n
Excellent ductility and crack resistance
- recommended for restrained welds and good machinability.
n
Suitable for butt or fillet welds on
lower strength carbon steels. n
Applications include high speed lap
welds, build-up or repair welding prior to machining and buttering or cladding
operations. n
Usable with Unionmelt 80, 350, 350M
and 231 fluxes. n
Wire diameters: 1/16" (1.6 mm),
5/64" (2.0 mm), 3/32" (2.4 mm), 1/8" (3.2 mm), 5/32" (4.0 mm) & 3/16" (4.8
mm). Spoolarc
29S AWS Class
EM13K Description:
n
Moderate amount of manganese and silicon
(higher than Spoolarc 80) for rust and mill scale tolerance.
n
Ideally suited for high speed single
pass welding on light gauge steels. n
Higher silicon level reduces porosity
and pock marking. Good wetting action and even weld bead profile.
n
Some caution should be taken when used
with an active flux. n
Applications include structural supports,
spiral pipe, hot water tanks, and pressure vessel construction.
n
Usable with Unionmelt 231, 651VF, 429,
439, 429M, and 656 fluxes. n
Wire diameters: 1/16" (1.6 mm),
5/64" (2.0 mm), 3/32" (2.4 mm), 1/8" (3.2 mm), 5/32" (4.0 mm) & 3/16" (4.8
mm). Recommended
