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

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.

NOTE: Pipeliner elec- trodes are manufactured under lot control. A Certificate of Test show- ing actual deposit chem- istry and mechanical properties per AWS A5.29 is available on request from the factory for every lot of electrode. (Fax 216-383-8386).
