A metal cored wire for high strength applications (>890 MPa) developed for use with argon / carbon dioxide shielding gas. Optimal mechanical and welding results are achieved with Ar/8%CO2 gas mixture. Excellent -40 degrees C toughness is acheived along with low diffusible hydrogen. The application area is anywhere where high strength steels are to be joined for example cranes, forestry machinery, load support and handling equipment.
