High fracture toughness welds in thick workpieces
Embodiments of flux cored welding electrodes and methods of use thereof are disclosed. The flux cored welding electrodes limit brittleness of flux cored arc welds, particularly in thick weld deposits. Limiting brittleness in thick (e.g., from about 1" to about 6") flux cored arc welds is a...

Zusammenfassung: | Embodiments of flux cored welding electrodes and methods of use thereof are disclosed. The flux cored welding electrodes limit brittleness of flux cored arc welds, particularly in thick weld deposits. Limiting brittleness in thick (e.g., from about 1" to about 6") flux cored arc welds is achieved by utilizing flux cored welding electrodes having chemical compositions that reduce (as compared to presently marketed electrodes) or altogether eliminate niobium and vanadium from their chemical compositions. |
