METHOD OF ELECTROSLAG WELDING BY PLATE-TYPE ELECTRODES AND FLUX USED IN THE WELDING PROCESS

摘要

ABSTRACT OF THE DISCLOSUREThe invention relates to welding, and more particular-ly to electroslag welding by plate-type electrodes under theharmful influence of external magnetic fields of high magneticinduction. Parts to be welded are brought together to providea gap between their edges. The relationship between the sur-face area "B" of the gap, in the area "A" of the horizontalcross section of the welding electrode, and the area "C" of theprojection of welding pools surface, is expressed by the ratio:A:B:C = 1 : (1.2 to 1.5) : (2.5 to 4.5).For the given ratios of the areas, the open part of the weldingpool surface has such dimensions that the magnetic field of theplate-type electrode neutralizes the action of the strong ex-ternal magnetic fields and prevents molten metal from splashing.
