Self-Shielded Flux-Cored Wires

We offer for self-shielded flux-cored wires (FCAW-S) specific solutions for a variety of industries and applications.

Böhler Welding offers self-shielded flux-cored wires (FCAW-S) with specific solutions for Mild steel, Pipeline steel under the diamondspark and BÖHLER Pipeshield portfolios. For wear protection applications UTP offers self-shielded flux-cored wires (FCAW-S), produced both in seamless and in folded production technologies.

Main features and benefits of cored wires:

  • Excellent mechanical properties and corrision resistance of all weld metal
  • Moisture pick-up resistance for seamless wires
  • Reliable and consistent weld quality
  • Smooth welding characteristics
  • Lack of or minimum spatter formation
  • Minimum post welding cleaning
  • Increased productivity
  • Reduction of total welding costs
