  • Publication number: 20210229204
    Abstract: Systems for multi-wire submerged arc welding including a flux-cored wire electrode comprising an internal flux, the internal flux comprising about 5% to about 70% of a carbonate compound and less than 25% of calcium fluoride (CaF2) by weight of the flux; an external flux for submerged arc welding, are provided such that, after a submerged arc welding process, the systems provide a weld metal comprising nitrogen in an amount of less than 100 ppm. Methods of performing multi-wire submerged arc welding using a flux-cored electrode and an external flux are also described.
