Abstract

PURPOSE: To prevent the occurrence of transverse cracks on the two-back bead surface, by using materials of a high apparent density and a high refractoriness, where refractory materials are mixed with the fused flux, as the backing flux for one-side arc welding.
CONSTITUTION: The flux having 1.40W1.80g/cm3 apparent density and a high refractoriness is used as the flux used for flux-copper packing one-side arc welding. For the purpose of obtaining this flux, materials having a high melting point such as MgO, CaO, and Al2O3 are fused temporarily, and solid and high-density granular materials and refractory materials such as magnesia clinker, alumina, rutile, zircon sand, and olivine sand are mixed with a comparatively large grain size. Otherwise, the carbohydrate such as fruit sugar and grape sugar and ≥1W2 kinds of thermosetting resin for improvement of packing performance such as phenolic resin and furan resin are coated on the surface of the flux at rate 0.5W10% to produce the flux.
