Pipeliner
www.lincolnelectric.com
Optimum performance on vertical
down hot, fill and cap passes on
standard cross-country pipelines
and arctic grade pipe. Excellent
crack resistance, CTOD, and Charpy
V-Notch properties. Recommended for
API Pipe Grades X42 through X70.
WELDING POSITIONS
ADVANTAGE LINCOLN
• Produces quality welds in moderate
wind conditions with no tenting.
• Our quality driven manufacturing
system – certified to ISO 9001 –
and our exceptionally high grade raw
materials mean every coil of
Innershield delivers great arc

feedability.
• Manufactured to actual lot control.
Actual certificates of conformance
are available upon request.
TYPICAL APPLICATIONS
• Standard cross country pipelines.
• Arctic grade pipe.
• Use these wires instead of stick for
improved productivity on pipeline
projects.

(1) The strength and elongation properties reported were obtained from a .505” tensile specimen artificially aged at 220°F
(104°C) for 48 hours, as permitted by AWS A5.29-98. A naturally aged tensile specimen may take months to achieve the
specified properties. The time required for the natural aging of weld deposits is dependent upon ambient conditions, weld-
ment geometry, the metallurgical structure of the weld deposit and other factors.
