OK Tubrod 15.27 is a fully basic, flux-cored, tubular wire for the welding of high tensile strength steels such as HY100. The weld metal contains 2.5Ni, producing the additional benefit of low-temperature toughness down to -50°C. This wire is capable of welding in all positions and uses the dip transfer mode for the vertical-up technique, which can be further enhanced by the synergic pulsed process. Shielding gas Ar+20% CO2.
