welding-alloys.com 23 Tungsten carbides Cored welding wires filled with advanced tungsten carbides provide extreme resistance to abrasive wear. Cast tungsten carbides are added to the wire during the production process. With low welding parameters, these pass directly through the welding arc without melting, therefore it is vital to ensure an even distribution of WC in the welding deposit. If the welding parameters are too high, this will result in the carbides dropping to the bottom of the weld pool (resulting in reduced wear protection).
