Detalles

A mild steel, gas-shielded flux-cored wire designed to provide the high deposition rates and low temperature impact toughness required in many heavy fabrication applications.

Características

  • High Deposition Rates – increase weld deposition up to 14 lbs/hr out-of-position
  • Flat Bead Appearance – fast freezing slag for a flat bead shape and increased productivity in all positions
  • Wide Operating Range – operators can set the machine on a single setting and weld in all positions
  • Little or No Pre-Weld Clean up Required – weld over light rust, mill scale and primer
  • Low Temperature Impact Toughness – capable of exceeding 27 J (20 ft·lbf) at -40°C (-40°F)

Aplicaciones Típicas

  • Heavy fabrication
  • Mining
  • General fabrication
  • Structural
  • Applications requiring PWHT of mild steels

Posiciones de soldadura

  • All
