Welding Wire

Solid Wire (MIG)

Super–Arc L–56 (ER70S–6) — is a low carbon, high manganese, and very high silicon wire that features
no–flake copper coating.

This wire can be used for welding on metals with a medium–to–high presence of dirt, rust, or mill scale.

The wire provides:

  • excellent puddle fluidity,
  • bead profile,
  • spatter control.

STT–MIG — is a specialized solid wire with a copper coating for STT welding in shielding gas.

The chemical makeup is strictly controlled during manufacture of this wire, and there are special requirements made on the quality of coiling.

Special physical and mechanical properties of this wire make it suitable for use in automatic welding.

Flux–cored Wire (FCAW)

Gas Shielded (Outershield)

Outershield 70 — (E70T–1, 9) — excellent for flat and horizontal groove and fillet welds.

Designed for optimum performance on dirty plate (high levels of rust, oil, or mill scale).


Outershield HD70 (E70T–1H8, 9H8) — features high deposition rates, up to 20% more than many competitive wires.


Outershield 71 (E71T–1, 9) — an all–position wire with excellent bead wetting action that produces
the smoothest horizontal fillets.

Self–Shielded Wire (Innershield)

Innershield NR–207 and NR–207H (E71T8–K6) — optimum performance on vertical down, hot, fill and cap passes on standard cross–country pipelines and arctic grade pipe.

Recommended API Pipe Grades X42 through X70.

Welds are characterized by:

  • excellent crack resistance,
  • CTOD,
  • Charpy V–Notch properties.

Innershield NR–208H (E91T8–GH8) — is similar to NR–207 but with lower hydrogen content, higher strength and excellent performance in low temperatures.

Produces weld deposits exceeding 550 mPa (80,000 psi) yield strength with excellent low temperature impacts.

Recommended API Pipe Grade up to X80.
