18. dec 2018

THE FUTURE OF WEATHERING STEEL WELDING

WEATHER RESISTANT CORED WIRES FROM DIAMONDSPARK BY BÖHLER WELDING

The latest development of Böhler Welding within its premium diamondspark line covers a range of weather resistant seamless cored wires which stand out due to their highest welding performance and extreme toughness combined with a total resistance against moisture absorption.

With its diamondspark range Böhler Welding offers a vast range of premium quality seamless cored wires on the market. Since the product launch in September 2017 the range has grown to more than 70 seamless cored wires. With the latest addition the diamondspark range now also covers the segment of weather-resistant cored wires. Böhler Welding offers three seamless FCAW wires and one SAW-FCW in comibination with two different fluxes for weather resistant steel in their diamondspark range:

  • BÖHLER NiCu1 Ti T-FD (Rutile FCAW for all postions)
  • BÖHLER NiCu1 T-MC (Metalcored MCAW)
  • BÖHLER Kb NiCu1 T-FD (Basic FCAW)
  • BÖHLER SUBARC TNiCu1 / UV 306
  • BÖHLER SUBARC TNiCu1 / UV 400

Weathering steel is a group of steel alloys which were developed to avoid painting. Named by a US company after its main benefits CORrosion resistance and TENsile strength, the steel is often called COR-TEN (or CORTEN) steel.

That steel has a certain number of alloying elements, such as P, Cu, Cr, Ni, Mo added in order to increase its resistance to atmospheric corrosion. This is reached by forming an auto-protective oxide layer on the base metal.

Fields of Application of weather resistant steels:

  • General steel construction of Bridges
  • Containers and Tanks
  • Chimneys and Industrial filters
  • Architecture

The new weather resistant cored wires are not only designed in accordance to those requirements. As part of the diamondspark family the seamless cored wires offer highest welding performance combined with a total resistance against moisture absorption.
