摘要: Systems (100) for multi-wire submerged arc welding including a flux-cored wire electrode (102) comprising an internal flux, the internal flux comprising about 5 % to about 70 % of a carbonate compound and less than 25% of calcium fluoride (CaF 2 ) by weight of the flux; an external flux (104) for submerged arc welding, are provided such that, after a submerged arc welding process, the systems (100) provide a weld metal comprising nitrogen in an amount of less than 100 ppm. Methods (200) of performing multi-wire submerged arc welding using a flux-cored electrode (102) and an external flux (104) are also described.
