摘要： PURPOSE:To obtain excellent welding workability and stable mechanical performance by using the bond flux contg. specific rations of SiO2, Al2O3, MgO, T.Mn, CaF2, T.FeO, Na2O, K2O, T.CO2, and H2. CONSTITUTION:The bond flux for submerged arc welding having the compsn. contg., by weight %, 17 to 26 SiO2, 25 to 42 Al2O3, 13 to 20 MgO, 5 to 10 T.Mn, 17 to 20 CaF2, 0.1 to 7 T.FeO, 0.5 to 3.5 one or two kinds of Na2O and K2O, 0.05 to 0.5 T.CO2 and 10 to 50ppm H2 is used. This flux generates gases, such as CO2 and H2 having a shielding effect so that the excellent welding workability and the stable mechanical performance are obtd., further consumption of flux is decreased. This flux is particularly adequate for the flux for the high speed horizontal fillet welding and the downward multi-layer butt welding.

摘要： PURPOSE:To produce the title bond flux which reduces flux consumption and allows deep penetration welding by preparing the bond flux of the compsn. consisting of specific ratios of SiO2, Al2O3, T.Mn, CaF2, CaO, MgO, Na2O, K2O, and BaO. CONSTITUTION:The bond flux for submerged arc welding contg., by weight%, 35 to 48% SiO2, 1 to 10% Al2O3, 6 to 20% total Mn, 2 to 10% CaF2, 1 to 10% CaO, 15 to 25% MgO, 2.5 to 5.5% 1 or 2 kinds of Na2O and K2O, and 0.5 to 2.5% BaO is prepd. Submerged arc welding is executed by using this bond flux, by which the deep penetration welding is executed without impairing the welding workability, such as bead appearance and bead shape. The flux/wire consumption is thus reduced.

摘要： PROBLEM TO BE SOLVED: To provide a backing flux for one side welding capable of making practical use of resources by contriving the reclamation of a welding slug generated after submerged arc welding, excellent in hygroscopic resistance in the one side welding, and capable of forming easily a back bead having the uniform and appropriate excess weld height. SOLUTION: The welding slug generated by crushing the slug of a bond flux used for the submerged arc welding is used as a raw material powder, the welding slug is added in the content of 10 mass% or more against the total amount of other flux raw material and the welding slug, after carrying out granulation and baking using a bonding agent, a thermosetting resin is coated. This backing flux has 3.0 mm or less particle size, 1.20-1.80 g/cc bulk density, and the composition of the other flux raw material is SiO2 : 10-45 mass%, Al2 O3 : 2-25 mass%, MgO: 10-40 mass% and SiO2 +Al2 O3 : 25-50 mass%.
