HIGHER TOUGHNESS STEEL ALLOY WELD DEPOSITS AND FLUX-CORED WELDING ELECTRODES FOR PRODUCING HIGHER TOUGHNESS STEEL ALLOY WELD DEPOSITS

The present disclosure is directed to flux-cored welding electrodes designed to produce higher toughness steel alloy weld deposits, and to the higher toughness weld deposits themselves. The weld deposits may comprise less than 0.20 (or less than 0.15) weight percent silicon. The flux-cored welding e...

Beschreibung
Zusammenfassung:	The present disclosure is directed to flux-cored welding electrodes designed to produce higher toughness steel alloy weld deposits, and to the higher toughness weld deposits themselves. The weld deposits may comprise less than 0.20 (or less than 0.15) weight percent silicon. The flux-cored welding electrodes comprise a flux core and a tubular steel strip. The flux core may comprise, by weight percent of the electrode, 0.25-0.30% zirconium, 0.12-0.18% aluminum, and 0-0.11% silicon. The metallic zirconium, aluminum, and silicon may be added to the flux core in the form of silicon-zirconium metal powder and aluminum-zirconium metal powder.
