Abstract

PURPOSE: To realize captioned welding of thick plastes at high efficiency and high performance, by using baked, sintered flux of specified composition, and welding by 1 layer, 1 pass, specified thickness of deposition and welding speed up to the position under the specified gap of the groove of specified shape and dimensions.
CONSTITUTION: Calcined or sintered flux is used, of which composition should be, by wt%, as follows: Al2O3 5W38, SiO2≤23, TiO2≤25, ZrO2≤25, MnO≤15, of which one or more kinds totaling to 15W80; CaO≤25, MgO≤35, BaO≤30, of which one or more kinds totaling to 10W50; metal fluorides, as fluorine, totaling to 2.5W15; alkaline metal compounds, as oxides, totaling to 2W5; and metal powder by 0.2W3 as essential components. The shape of groove is roughly I- shaped, the depth of groove is H, the groove bottom and surface gap WB, WF are respectively 6W14mm and more than 12mm, and the formula is satisfied. At least, up to the position of groove gap(ce) less than 18mm, welding is performed by 1 layer, 1 pass, thickness of deposition=sectional area of deposition/groove width at 3W6mm, and welding speed at 15W40, or 20W70cm/min in the case of single electrode or two electrodes, respectively.
