Abstract | Provided is a sintered flux for submerged arc welding which is applied to austenite stainless steel welding. The flux includes 12.0-20.0wt% SiO2, 18.0-27.0wt% Al2O3, 6.0-12.0wt% ZrO2 6.0-12.0wt% CaO, 7.0-16.0wt% CaF 2, 2.0-5.0wt% MnO, 20.0-29.0wt% MgO, 1.5-4.5wt% Na 203, K 20, Li 20, or a combination thereof, and a remainder including Fe and inevitable impurities, on the basis of the entire weight of the flux. Therefore, it is possible to provide a sintered flux for submerged arc welding which has excellent arc stability and slag detachability during welding, prevents welding defects such as poke marks and pits, and has excellent bead shape.
L'invention porte sur un flux fritté de soudage à l'arc sous flux pour le soudage de l'acier inoxydable austénitique, Le flux comporte: 12,0-20,0% en poids de SiO2, 18,0-27,0 % en poids de Al2O3, 6,0-12,0% en poids de ZrO2, 6,0-12,0% en poids de CaO, 7,0-16,0% en poids de CaF, 2, 2,0-5,0% en poids de MnO, 20,0-29,0% en poids de MgO, 1,5-4,5% en poids de Na2O3, K2O, Li2O, ou leur combinaison, le reliquat étant du Fe et les impuretés inévitables, et cela sur la base du poids total du flux. On obtient ainsi un flux fritté assurant une excellente stabilité d'arc et l'élimination des scories pendant le soudage, empêchant les défauts de soudure tels que les piqûres et les criques, et donnant des perles d'une forme excellente. |
