FLUX FOR USE IN SUBMERGED ARC WELDING
To provide a flux for submerged arc welding that has good welding workability and can reduce the moisture-absorption amount of the flux and the diffusion hydrogen content in a weld metal, even in the use of either an alternating current or a direct current welding power source. The flux for submerged arc welding is set at the composition including: Al 2 O 3 : 15 to 35% by mass; SiO 2 : 10 to 30% by mass; MgO: 10 to 25% by mass; F in terms of CaF 2 : 10 to 25% by mass; Mn in terms of MnO: 3 to 20% by mass; a total of at least one or more of Na in terms of Na 2 O, K in terms of K 2 O and Li in terms of Li 2 O: 0.5 to 6.5% by mass; Fe in terms of FeO: 0.5 to 8% by mass; CaO: 6% by mass or less (including 0% by mass); TiO 2 : 8% by mass or less (including 0% by mass); water-soluble SiO 2 : 1.0% by mass or less (including 0% by mass); water-soluble Na 2 O: 1.0% by mass or less (including 0% by mass) ; and water-soluble K 2 O: 0.8% by mass or less (including 0% by mass), wherein a C content is 0.2% by mass or less (including 0% by mass), and the flux satisfies the following numerical expression (I), where [Al 2 O 3 ] is the Al 2 O 3 content, [MgO] is the MgO content, and [MnO] is a content as the Mn in terms of MnO. 0.20 ¦ MgO A l 2 O 3 + MnO ¦ 0.80
