Characteristics and application TIG/GTAW rod for weathering steels. Weathering steels, with controlled additions of Cu, provide improved corrosion resistance compared to CMn steels. The improved resistance to atmospheric corrosion means these steels find use for architectural applications and also for welding CMn steels to prevent preferential corrosion of the weld.
Base materials For weather resistant construction steels, commonly referred to as weathering steels.
