All-State
616 MEGA II Super
Coated and Moisture Resistant DC
(+) or AC General
Characteristics This
electrode, which is low hydrogen in nature, is above others of its type because
of its high mechanical properties
as well as easy weldability. Has excellent slag removal, easy strike-restrike
capabilities, good for rusty metal
and other contaminants found on steels. It’s specially suited for welding
in awkward positions including vertical
down. Performs well on AC current. Typical
Applications Because
its special coating gives excellent resistance to moisture pick-up, 616 MEGA II
is ideal for use in places where
low hydrogen electrodes are difficult to keep dry, such as mines, logging operations,
shipyards, paper mills, and
construction sites. Use for welding from low to high carbon steels, low alloy
steels, structural steels, cast steels,
including a variety of hardenable steels. Excellent for maintenance of machinery
components. Qualities
Yield Strength
—up to 59,000 psi (up to 410 N/mm2)
Tensile Strength
—up to 79,000 psi (up to 550 N/mm2)
Elongation
—32%
Machinability
—Excellent
Procedure Clean
base metal. Preheat generally not required but should be used with hardenable
steels. Preheat may also be required
when welding heavy sections. Hold a short arc with a slight lean in the direction
of travel. If electrodes become
damp, they may be redried for 2-3 hours at 500-550° F (260-290° C).
