Innershield® NS-3M

Flux-cored self-shielded (FCAW-S) Wire

AWS: E70T-4, E70T4-AZ-CS3

Innershield® NS-3M from Lincoln Electric is designed for very high deposition rates and increased resistance to hydrogen cracking and porosity on steel containing sulfur or contaminates.

DETAILS

Designed for very high deposition rates and increased resistance to hydrogen cracking and porosity on steel containing sulfur or contaminates. Recommended for single or multiple pass welding on carbon steel and some low alloy steels in applications without impact strength requirements.

Features

  • Very high deposition rates
  • Increased resistance to hydrogen cracking and porosity
  • Soft, low penetrating arc for minimal base material admixture

Typical Applications

  • Open groove welds
  • Machinery bases and heavy equipment repair
  • Installing wear plates
  • 6.4 - 12.7 mm (1/4 - 1/2 in) single pass fillet and lap welds

Welding Positions

  • Flat/Horizontal

Shielding Gas

  • N/A
