OK Tubrod 15.00S

Filler MetalsFlux-Cored Wire

OK Tubrod 15.00S is a basic gas‑shielded flux‑cored wire designed for submerged arc welding (SAW). It delivers flat welds with deep penetration, high deposition rates and increased productivity.

Key Features

  • Flat welds with deep penetration and excellent wetting
  • High deposition rates and efficiencies, reducing weld time
  • Suitable for productive positional welding
  • Low diffusible hydrogen levels (H5) when required
  • Developed for demanding applications such as structural steel, heavy equipment, bridges and shipbuilding

Specifications

  • Welding Current: DC+, AC
  • Diffusible Hydrogen: <5 ml/100 g
  • Alloy Type: C Mn
  • Diameter options: 2.4 mm, 3.0 mm, 4.0 mm
  • Amps range: 250‑900 A (depending on diameter)
  • Voltage: 28‑40 V
  • Wire feed speed: 1.5‑6.0 m/min
  • Deposition rate: 3.5‑18 kg/h
  • Approvals: DB 52.039.14, ABS 3YM, BV A3YM, CE EN 13479, DNV‑GL III YM, LR 3YM, PRS 3YM, UKCA EN 13479, VdTÜV 09144

Applications

  • Structural steel construction
  • Heavy equipment and transportation
  • Bridges and offshore rigs
